Welder shortcomings in the process of using the welder will have a certain magnetic field around
Disadvantages of welding machine In the process of using the welder will produce a certain magnetic field around the arc burning will produce radiation around the arc in the infrared, ultraviolet and other light species, as well as metal steam and smoke and other harmful substances, so the operation Adequate protective measures must be done. Welding is not suitable for high-carbon steel welding, welding seam metal crystallization and segregation and oxidation process, the poor performance of high-carbon steel welding, cracking easily after welding, resulting in hot cracks and cold cracks. Low-carbon steel has good welding performance, but the process should be properly handled, rust cleaning is more cumbersome, and sometimes weld defects such as slag undercut cracking holes, but the proper operation will reduce the defects.
