Disadvantages In The Use Of The Welding Machine Process

Disadvantage in using the welder welding machine will have a certain magnetic field around, arc Burns, radiation around the arc light in the infrared, ultraviolet light, such as species, and metal vapor and smoke and other harmful substances, so the operation must be done when sufficient protective measures. Welding is not suitable for welding of high carbon steel due to welding processes such as crystallization and segregation and oxidation of the weld metal, for high carbon steel welding performance, after easily cracking, thermal cracking and cold cracking. Welding of low carbon steel has a good performance, but of course also to operate properly, rust removing cleaning more cumbersome, sometimes weld slag appears crack defects such as pores undercut, but done properly will reduce defects.
