Metline is a specialized supplier of ASTM Are Quenched and Tempered (Q&T) Steels Readily Weldable?Also denoted by QT or Q/T, these steels are weldable, but care must be taken to adhere to established procedures at all times, as they often have high carbon contents, and thus high hardenability, leading to a hard heat-affected-zone (HAZ) and susceptibility to cracking. The BS EN 10277-5:2008 (old BS 970 Part 3) steels are good examples of these types of steel.

Jun 15, 2020 · Tips for MIG welding:Prepare your push-pull wire feed. Clean your aluminum, remove any oxide and file the edges that will be joined. Avoid pulling while weldinginstead, push at a 10 to 15 degree angle. Use multiple pass straight beads to improve the overall appearance of Influence of cold-wire tandem submerged arc welding May 30, 2016 · Tandem submerged arc welding with an additional cold-wire (CWTSAW) is being developed for pipeline manufacturing to improve productivity in terms of deposition rate and travel speed of welding. An appropriate understanding of the welding conditions to guarantee requisite weld geometry, appearance, and mechanical properties is always essential in the development of a welding
