  • Effect of Different Veneer-Joint Forms and Allocations on Mechanical Properties of Bamboo-Bundle Laminated Veneer Lumber
    PEER-REVIEWED ARTICLE bioresources.com Effect of Different Veneer-joint Forms and Allocations on Mechanical Properties of Bamboo-bundle Laminated Veneer Lumber Dan Zhang, Ge Wang,* and Wenhan Ren Bamboo-bundle laminated veneer lumber (BLVL) was produced by veneer lengthening technology. The objective of this study was to evaluate the effect of different veneer-joint forms and allocations on the mechanical properties of BLVL. Four veneer-joint forms, i.e., butt joint, lap joint, toe joint, and tape joint, and three lap-joint allocations, i.e., invariable allocation (Type I), staggered allocation (Type II), and uniform allocation (Type III), were investigated in laminates. The results revealed that the mechanical properties of veneer-joint BLVL were reduced in comparison with that of un-jointed BLVL. It was found that the best veneer-joint form was the lap joint laminate, of which the tensile strength, modulus of elasticity, and modulus of rupture values were reduced by 38.41%, 0.66%, and 10.92%, respectively, when compared to the un- jointed control samples. Type III showed the lowest influence on bending and tensile properties, followed by Type II.

  • Woodworking Joints.Key
    Woodworking making joints Using Joints Basic Butt Joint The butt joint is the most basic woodworking joint. Commonly used when framing walls in conventional, stick-framed homes, this joint relies on mechanical fasteners to hold the two pieces of stock in place. Learn how to build a proper butt joint, and when to use it on your woodworking projects. Basic Butt Joint The simplest of joints is a butt joint - so called because one piece of stock is butted up against another, then fixed in place, most commonly with nails or screws. The addition of glue will add some strength, but the joint relies primarily upon its mechanical fixings. ! These joints can be used in making simple boxes or frames, providing that there will not be too much stress on the joint, or that the materials used will take nails or screws reliably. Butt joints are probably strongest when fixed using glued dowels. Mitered Butt Joint ! A mitered butt joint is basically the same as a basic butt joint, except that the two boards are joined at an angle (instead of square to one another). The advantage is that the mitered butt joint will not show any end grain, and as such is a bit more aesthetically pleasing. Learn how to create a clean mitered butt joint. Mitered Butt Joint The simplest joint that requires any form of cutting is a miter joint - in effect this is an angled butt joint, usually relying on glue alone to construct it. It requires accurate 45° cutting, however, if the perfect 90° corner is to result.

  • Investigation of Strength of V & U Groove Butt Joint by Tig
    Vol-2 Issue-1 2016 IJARIIE-ISSN(O)-2395-4396 INVESTIGATION OF STRENGTH OF V & U GROOVE BUTT JOINT BY TIG WELDING & IT’S ANALYSIS N.B.Landge1, Dr.Y.R.Kharde2 1M.E Student, Department Of Mechanical Engineering,Pravara Rural Engineering College,Loni- Maharashtra. 2Professor, Department Of Mechanical Engineering,Pravara Rural Engineering College,Loni- Maharashtra. ABSTRACT Welding, one of the most convenient and rapid method used for joining metals in navy, process industry in fabrication, maintenance, repair of parts and structures. The plates used in process industry has welding strength as its important parameter. In this paper investigation of V & U groove geometry to find out tensile and impact strength in case of butt weld joint will be done. For V & U groove geometry different models of plates with varying included angle from 300, 450, 500 will be made. Currently the V-groove geometry with included angle up to 300 is in use, after studying the Indian Welding Journal, Indian Welding Society it is observed that distortion and residual stresses increases with increase in groove angle and its strength also increases with groove angle increasing the weld material which affect the economy of welding. In this paper we aim at overcoming these disadvantages by making use of V & U groove. Tensile test to check maximum tensile force sustaining capacity and micro and macro inspection test to check welding quality and other parameters has been conducted. Other tests carried out includes impact test to check maximum energy absorbing capacity, we also measured dimensions of specimen before and after welding to find out longitudinal and transverse distortion if any by making use of four specimens.

  • PLEXIGLAS® SHEET: Cementing and Troubleshooting
    Technical information PLEXIGLAS® SHEET: Cementing and Troubleshooting Option 1: SOLVENT CEMENTING RECOMMENDATIONS Use methylene dichloride (MDC) as the basic cement. Add up to 10% diacetone alcohol to reduce blushing caused by the evaporation of solvent in humid conditions. Use the following solvent cement mixture for optimum joint appearance: 70% MDC, 20% MMA (methyl methacrylate inhibited monomer) and 10% GAA (glacial acetic acid). Store solvent cements in vapor-proof/corrosion-proof containers, such as glass or plastic-coated metal. Use only enough solvent to wet the joints, since excessive solvent will increase set times and possibly result in whitening or crazing. Do not flow or drip solvent on any flame polished, strip heated or dry-belt sanded surfaces. When soak cementing, limit soak time to approximately 45 seconds. The optimum edge finish is one which has been cut by a skim router (approximately .030" removal). Do not force fit parts to be cemented. Cementing Technique: Capillary Action Method The parts must be closely fitted with no visible gaps. The parts to be cemented should be unclamped or lightly clamped together. The cement is dispensed (from a hypodermic needle or eye dropper) along the joint. Capillary action draws the cement between the parts. Time for the joint to set varies from 2-5 minutes depending on the solvent used and temperature and humidity. Do not flow or drip solvent cement on a flame-polished, strip-heated or dry-belt sanded surface as these conditions show the maximum fabrication stress possible in plastic sheet. Cementing Technique: Soak Dip Method The parts must be closely fitted with no visible gaps.

  • HVAC Noise Control
    FUNDAMENTALS OF ARC WELDING Welding is the process of joining two pieces of metal by intense heating with or without the application of pressure or by the application of pressure alone (without heating) and with or without the use of filler material. It is distinguished from other forms of mechanical connections, such as riveting or bolting, which involves friction or mechanical interlocking. Welding offers many advantages over riveting or bolting: 1. Welded structures are more rigid compared to structures with riveted and bolted connections; 2. Welding gives the appearance of a one-piece construction as against the cluttered surface of bolted or riveted connections; 3. Welded structures allow the elimination of a large percentage of the gusset and splice plates necessary for riveted or bolted structures. 4. Welding saves up to 15% of the steel weight and economies are achieved due to elimination of operations like drilling and punching, It also saves time in detailing and fabrication; 5. The strength of the welded joint equals or exceeds the strength of the original base metal, thereby placing no restriction on the joints; 6. Weld connections offer the designer more freedom for innovation in his design, make changes and to correct mistakes during erection; 7. Welding is practicable for almost all types/shapes of joints; for example, connection of a steel pipe column to other members; 8. Welding offers air tight and water tight joining of plates and hence ideal for oil storage tanks, ships etc. Some disadvantages: 1. Skilled manpower is needed for operation and inspection of welded connections; 2. Welded joints are highly prone to cracking under fatigue loading - non-destructive evaluation may have to be carried out to detect defects in welds; 3.
