The second month into the program I decided to take the certification test. Our school was a testing facility so I paid out of pocket to take the test along with other guys in the industry, and I passed. That gave me the validation that I was doing the right thing. I worked at a place that made subassemblies for G.A. Braun Inc. I went there while I was still in welding school to see if they were hiring. The secretary said they weren’t, but that I could leave my resume behind. So I ran out to my truck and grabbed it, and when I got to the front door, the owner was there waiting for me. He liked my hustle and hired me. I realized right away that I was in over my head. I Bowman has always been passionate and had been studying stick welding in school, but these energetic about welding. But at times in his guys were doing mostly MIG. I had so little experi- career he’s felt others in the industry have ence with MIG, especially short-circuit on stainless looked down on him for it. steel. I realized I had been missing out on quite a bit by focusing on stick welding. At that point I was ready to leave school. I didn’t care if I didn’t get my certificate of completion—I had already earned my certification.

TW: You’ve had a difficult time finding the right fit professionally. What have been the biggest takeaways from those experiences? NB: I’m 33 years old now. If people want to say things about me or make fun of me, that’s fine. I’m very happy with where I’m at right now, but looking back on the stuff I dealt with and how much of a battle it was for me, that’s what fueled me. It’s why I do the things I do now. I’ve always felt like people looked down on me for being so passionate about this trade. I just try to show people that it’s OK to be different than other people. It’s OK to be a welder and be smart. A lot of welders buy into the perception that welders are dirty and dumb so they don’t realize how valuable their skills are or how much they are worth and they end up staying at a crappy job forever. You have to be your own advocate and be brave enough to put yourself in an environment that’s rewarding for you and where you feel valued.

TW:: Tell us about what you’re doing currently. NB: I’m the director of welding optimization and education at Central Welding Supply in Vancouver, Wash.

Second, when we talk about a skills gap, I think some high schools and community colleges do a poor job of preparing students for employment. Many instructors rely on passing down knowledge in the same way they were taught. But we have to ask ourselves, why? Is that really the best way to do it? There are so many jobs that require skills in MIG, flux-core, and TIG. Why do weld classes spend the first month practicing how to oxyacetylene weld? When’s the last time you saw that in industry? And the argument that oxyacetylene welding is just like TIG just doesn’t add up. It might be similar in one way, but saying that gives people a completely false understanding of heat input and how it works, and it convinces people that welding with fire is the same as welding with electricity, and it isn’t. This has happened to me. When I took that welding class back in New York, my instructor insisted that we all get a structural steel SMAW certification. Well, I’ve used it one time since then. Third, I think there’s an unwillingness for people to jump ship when their employer sucks. I worked with a guy once who spent 37 years with the company and was one of the most talented welders I’ve ever seen in my life. But he lived in a shack and drove a crappy car and was not earning what I felt he deserved. So, I thought to myself, Is this where The fact that Bowman has earned his CWI, CWE, and CWS credentials gives further weight to his words. I’m headed? At that point I had already battled the owner to give me 50 cents more an hour. If that was the case for me, what was this guy making after 37 years? I think high school and community colleges would benefit from having a system in place to connect students with local job opportunities. That’s something I’m working on at my job. Eventually I’d like to have an internal jobs board where our customers can post job openings, and from there local weld instructors can take a look at that and guide students who have the skill set needed toward these employers.

TW: Are young welders too often unfairly stereotyped as being lazy and unmotivated? NB: I don’t think younger people are necessarily less motivated, I just think they feel their ideas get shot down immediately. I remember getting shot down all the time, and now I see that happening to others in industry. I think that begins to wear on you after a while and you begin to lose that energy that you had when you first started. I’ve been doing this for 18 years and I still don’t know everything. I don’t believe I ever will. I have

Compared to a Class A weld, the tensile shear strength of a single Class C spot weld is only reduced from 1,820 lbs. to 1,600 lbs., but products look much better with an attractive, low-marking Class A weld made with a properly sized spot welding machine. Plus, in a production line environment, Class A weld nuggets will be consistently strong and electrode life will be much longer.

INVEST IN SETUP TOOLS Adding to the mystery of the process, most resistance welding controls lack readouts for welding amps and force. Therefore, to adjust these important variables properly, it’s a good idea to invest in a specialized portable resistance welding amp meter and force gauge.

SELECTING THE RIGHT WELDING SCHEDULE Charts that list Class A, B, and C machine settings for various metal thicknesses are included in reference books such as RWMA’s Resistance Welding Manual, Revised 4th Edition. Although still relatively strong, Class C welds often are considered unacceptable because of the large heat-affected zone (HAZ) resulting from an extended weld time. As an example, Class A spot welding specifications for two pieces of clean 18-ga., low-carbon steel are 10,300 welding amps, 650 lbs. of weld force, and 8 cycles of weld time. (One cycle is only 1 ⁄60 second, so eight cycles is very quick.) A Class C welding schedule for the same steel combination is 6,100 amps, 205 lbs. of force, and a whopping 42 cycles of weld current flow. This extended weld time of well over half a second may overheat the electrodes, create an extremely Most resistance welding controls lack readouts for welding amps and force.

IMPORTANCE OF WATER COOLING Spot welding machine components must be properly water-cooled to ensure quality welds and long electrode life during production runs. Some shops use small, nonrefrigerated, radiator-type water recirculators that, at best, can deliver water near room temperature. These recirculators can negatively affect production rates when spot welding tips mushroom from the heat and require dressing or replacement several times a shift. Since the ideal water temperature for resistance welding machines is 55 to 65 degrees F (or above the BUILT FOR prevailing dew point to prevent condensation), it’s best to connect the machine to a self-contained refrigerated water chiller/recirculator.

BRINGING A METALWORKING COMMUNITY TOGETHER Even though Hunter knew she was never going to be a career welder, the new skill set allowed her to expand upon her artistic abilities.

We have longer, broader classes that teach them how to use the tools, the techniques, and the handiwork that goes into working with metal jewelry. I offer a couple of different TIG welding workshops—some where people come in and learn a little bit each week and others that are project- based. People like making things they can take home with them and say that they welded it, like a planter or a table,” Hunter explained. It’s been a rewarding experience for Hunter to see people working together, sharing knowledge, and enjoying learning something new. While 2020 was difficult, she made the appropriate adjustments to provide a safe working environment amid COVID-19. In addition to appreciating the community The Hot Spot brings together, Hunter loves witnessing someone’s aha moment. “I get so excited when it clicks with my students. Maybe their welds aren’t perfect, but you know they’ve got it and are really into what they’re doing. I just tell them to keep going, stay in that moment, and remember what your hands are doing; remember the pace at which you’re laying the bead, and what E your posture feels like, and keep on rolling.” TH

For the love of all that is welding

By Josh Welton

I love welding. It’s fueled a passion inside of me that’s been forged into a sharp, double-edged sword. On one side is my love for the craft and a wish for all comers to experience the thing that gives me so much joy. On the other is a desire to see the welding and fabrication industry as a whole improve, especially in taking better care of its workforce. This second side garners a bit of flak from those in the industry who like to twist my words into something they are not. Yes, I think some organizations say they support and advocate for welders but are actually more concerned with profiting from welders. Yes, I’ll fight tooth and nail to present accurate, realistic numbers about job availability and what you can expect to earn, unlike certain industry groups and talking heads. But it comes from a place of my absolute love for the game. I love welding. A plethora of factors go into this long-running affair, and in the spirit of positivity, I’d like to ruminate on a few of them. It was love at first arc when I first struck one back in 2002 with a 6010 stick. Watching through the smoky haze as the metal flowed, smelling the burning rust and flux, feeling the

electrical surge between the ground and the electrode tickling my nerves, hearing my classmates yelling at me “You’re on fire! Your pants are on fire!” That’ll forever be in my heart. Welding doesn’t suffer fools lightly. It’s honest. The proof is in the pudding. Every action causes a reaction, and the metal doesn’t lie. A shimmy here or a shake there, your work angle, arc length, travel speed all read like a book printed in metal. If you leave a little flux in the toes between passes, it’s going to show up in a scan or a break. A weld bead, both on the surface and below, viewed through an X-ray machine and with the naked eye, is a direct reflection of your ability. Get knocked for too many inclusions?

you’ll be flipping pancakes again in no time. Even in the worst of times, welding will prove to be necessary for a life worth living. A strong community of like-minded people who are willing to share their knowledge and experiences has exploded onto the social media scene. Welders at the top of their game have become both teachers and rock stars, sometimes at the same time. Kids coming up have no shortage of accessible role models and an insane amount of resources at their disposal. That doesn’t make learning to weld or making it as a welder easy. Nothing worthwhile comes easy. There are real, tangible obstacles on the journey to welding nirvana. It’s not a path for the faint of heart, nor for those without passion or determination. It’s a course navigated through will and desire. E And it’s absolutely worth the payoff. TH

There’s a general fascination with welding, too, way beyond those of us who do it day in and day out. It’s a conversation starter. From hipsters to Wall Street sharks, people dig the concept, and let’s face it, playing with fire and harnessing its power brings with it a certain amount of street cred. It’s hot, and dirty, and dangerous. You’re harnessing the elements to create something out of nothing. In a tem- poral world, you can bring something to life nearly as eternal as anything else on earth. You’re not stuck in a cubicle, staring at a screen, or attending boring meetings. You’re out in the flesh-and-blood world, creating and maintaining our matrix. It’s also nice having the peace of mind that when shit hits the fan, you’ll be able to weld your way out of trouble in a dystopian future. Nuclear apocalypse? Mad Max didn’t hot-glue his Intercep- tor together. Kaiju attack? The mechas didn’t build themselves. Exodus to Mars? We’ll need space- ships to get there and infrastructure when we arrive.

When I answer, will prompt dissent from the opposing we follow a welding procedure specification, we side. Let me begin by addressing this question: are following a process.

QuantumBrochureWithBleed.indd 15 2/17/21 4:37 PM A welding table from Siegmund® can save up to 40% of your production time!

Thanks to the high accuracy of the Siegmund® welding and clamping tables you can work much faster and more precise with reliable lower fabrication errors.

Within a very short time you can arrange many applications with the Siegmund® modular system. This reduces set-up times and saves storage space and costs.

Calculate for yourself!

SAMPLE CALCULATION:

Hypothetical costs for fabricator/welder per year incl. additional expenses: $60,000

The savings potential is around 40 % during the production of prototypes with high down times. $24,000

that equals

A realistic life span of 10 years on a table system is equivalent to a cost savings of: $240,000
