Distortion is an inherent #welding phenomenon that could be controlled by Design The following design principles can control distortion: 👉eliminate welding by forming the plate and using rolled or extruded sections 👉minimise the amount of weld metal do not over weld 👉use intermittent welding in preference to a continuous weld pass 👉place welds about the neutral axis balance the welding about the middle of the joint 👉 by using a double-V joint in preference to a single-V joint

When should you opt for resistance welding? Resistance welding works on the principle that when an electric current is passed through metal, the resistance of the metal to the electric current generates heat. This heat, combined with the pressure applied to the workpieces, causes the metal at the joint to melt and fuse together, forming a weld. There are many methods of resistance welding, such as spot, seam, projection or flash welding. Each one takes a different approach to the same principle, resulting in a variety of welds appropriate for different applications and industries. It's most commonly used to join sheet metal or other thin materials (like the wire you see here) where form and function are both critical. With no need to introduce new materials, the result is a clean, durable weld that serves both purposes. #resistanceweld #welding #weldernation #migweld #tigweld #spotwelding

Grappling with the new methodologies for weld neck flanges? In our recent Flange Webinar, our engineers at CEI, Finglow, and Paulin Research Group delved into this topic. To simplify the design process, they've innovated solutions that streamline validation checks against these new methods and facilitate designers during their modelling work. DesignCalcs and Finglow cover global codes from ASME Section VIII, Div 1 and 2, EN 13445, and PD 5500. These solutions make designing and analyzing flanges in compliance with different codes much more straightforward.

𝗪𝗵𝗮𝘁 𝗶𝘀 𝗨𝗻𝗱𝗲𝗿𝗰𝘂𝘁? Undercut is a common welding defect and this happens because the welding heat has melted away more base metal than desired, creating a groove or notch along the toes of the weld. 𝗛𝗼𝘄 𝗨𝗻𝗱𝗲𝗿𝗰𝘂𝘁 𝗢𝗰𝗰𝘂𝗿𝘀? ￫ Too high current can create an arc that penetrates too deeply into the base metal, which overheats and removes metal below the weld. ￫ Fast Travel Speed and moving the welding torch too quickly, which can cause uneven melting and undercutting along the edges. ￫ Making too many zigzag movements on the electrode. ￫ Holding the torch at too sharp of an angle focuses the arc onto the base metal, eroding it away. ￫ Contaminated base metal with paint, rust, mill scale on the surface. 𝗥𝗲𝗽𝗮𝗶𝗿𝗶𝗻𝗴 𝗨𝗻𝗱𝗲𝗿𝗰𝘂𝘁: ￫ 𝙈𝙞𝙣𝙤𝙧 𝙪𝙣𝙙𝙚𝙧𝙘𝙪𝙩 can often be repaired by simply re-welding over it. The new weld metal will fill the groove and build up the edge. ￫ 𝙁𝙤𝙧 𝙡𝙖𝙧𝙜𝙚𝙧 𝙪𝙣𝙙𝙚𝙧𝙘𝙪𝙩: - Grind or file out the undercut defect to form a groove with sloped sides to remove all affected weld metal. - Fill the ground-out area with w

Introducing the CS-51B, an automatic welding machine that can weld both sides of a horizontal fillet simultaneously using two torches. With two torches welding side by side at a constant distance, it is effective for welding thick workpieces and can save costs and time. The machine is widely used in fabrication (small assembly) and operates along the welding line with permanent magnets on the bottom of the machine. It is easy to attach and detach with a handle lever, and it can also perform continuous welding. It is convenient with an automatic stop function at the end of the sensor, and the carriage arm height can be adjusted according to the height of the workpiece. With these features, the CS-51B can be utilized in various industries. It is useful in cases where thick workpieces need to be welded or where a large amount of welding needs to be done quickly.

Soldering and welding both have distinct advantages and disadvantages depending on the application. Welding produces a much stronger joint than soldering. This makes it suitable for load-bearing and structural metal connections. Soldering only makes a connection as strong as the solder you use. Welding two different metals together is generally not possible without specialist equipment and techniques. In comparison, soldering with certain types of solder allows you to join any two metals together.

Han's Laser Hybrid Laser Welding Application in the Cabinet Industry In the cabinet industry, this technology could be particularly beneficial for producing strong, durable joints quickly and efficiently. This is especially valuable in an industry where both the structural integrity and appearance of the product are important. The precision and control provided by laser welding also allow for finer work on the thin metals often used in cabinet designs, minimizing distortions and reducing the need for post-weld finishing. Are you looking for information on how technology is specifically changing the cabinet industry, or are you interested in a different aspect of this field? #HybridWelding #MetalWelding #Welding #LaserWelding #CabinetWelding #CabinetIndustry #WeldingApplication #Hanslaser

When running GMAW spray-arc, undercut on the topside of a horizontal fillet weld is often times caused by poor work angle. Meaning the angle of the electrode is more towards plate A then plate B. This can be corrected by dropping your work angle from 45°+ down to 35-45° in relation to plate B without a need to adjust weld settings. Other causes can be travel speed, excessive voltage/amperage or arc length. If the undercut is found to be deeper than the acceptable limits of the code it will need to be rewelded. #fabrication #welding #gmaw #weldinginspector #production #manufacturing #engineering #qualitycontrol #steelstructures
