Controlling Warping On Sheet Metal

If there isn t a lot of rust on the sheet metal softer abrasives like walnut shell soda blast crushed glass or plastic beads are sometimes used to reduce warping of sheet metal.

Controlling warping on sheet metal.

As a rule of thumb it s better to weld as hot and fast as possible to get in and out of the weld as quick as you can. This relaxes the metal and flattens the weld which in the end allows you to control the warpage in the panel. An ounce of prevention the battle between hot cold. Design and welding should be addressed to minimize this sort of warping.

This is very important to keep the shape of the panel you re welding. Correctly sizing a weld not only minimizes distortion but also saves weld metal and time. Use intermittent welds instead of continuous welds where possible to minimize the amount of weld metal. Even seasoned pros who perhaps haven t had a serious issue with a warped piece of sheet metal in a long time can gain new insight from some of these tips.

Intermittent rather than continuous welds help as does minimizing the. Work hot and fast a lot of damage or excessive warping when welding could be from dwelling too long in a small area when welding. Use anti warping devices and techniques. The warping of metal during the welding process is due to the high levels of heat involved.

Preset the pieces sometimes called counter or opposing set up this means allowing for the. Aggressive abrasives like coal slag or aluminum oxide generates more heat and peening. The bigger the weld the greater the shrinkage. By putting the metal between a dolly and a swinging hammer you are slowly stretching the metal out by striking on it each time think of kneading pizza dough.
