I would also try to clamp a copper or aluminum plate under the weld area as a heat sink. Jan 14, 2016 / Can I repair bush hog sheet metal with .
It worked OK but if you put enough heat in to the steel to get a good weld you usually melted the copper and it stuck to the back of your weld anyway. . it also acts like a heat sink and copper doesn't stick as easy to your work like a steel backing would. . Copper can stick, maybe more so with copper sheet metal but it wasn't an issue for . Combining the microscopic results of the weld seam (Fig. 10) and the residual stress of the weld seam (Fig. 7), it was found that the residual stress and microstructure of the weld seam were significantly improved in the ultrasonic + heat sink composite assisted welding scheme. Therefore, it can be concluded that the ultrasonic + heat sink .
The weld initially looks bad because of the slag from flux core welding. Spatter. Tiny beads of metal also get left behind after flux core welding which can create more grinding work. Porosity. You’ll get tiny holes or pockets of contamination in your weld. Blow out. This is when your sheet metal literally blows out the sheet metal into . Try supporting your metal from the backside with something. Having something like a table underneath or even a little copper backer will help support that molten weld pool and it will act like a little bit of a heat sink. You want to avoid welding sheet metal that’s floating in .Even heat sinks are not very effective with stainless steel. . Essential Equipment and Settings for Thin Sheet Metal Welding. Now that we have established what problems you will be facing, let’s start with selecting the right equipment before moving on to the solutions for those problems.
