The use of stainless steel is becoming more and more common, no matter in life or production, so we need to have a deeper understanding of it. This article discusses the common welding methods of stainless steel.
First, hand soldering. Manual welding is a particularly common and commonly used welding method that is simple to operate and convenient to use. The length of the arc can be reasonably adjusted manually by the operator, and the adjustment is carried out according to the gap between the electrode and the workpiece to be welded, and the length of the arc is adjusted according to the size of the gap. The welding rod can not only be used as a tool for welding stainless steel, but also can be used as an effective filling material for the weld under certain circumstances. And this material can better join stainless steel workpieces to achieve better compatibility.
Secondly, metal electrode gas-shielded welding. Metal gas-shielded welding is an automatic gas-shielded arc welding. In the process of using this method, the arc is ignited and welded between the welding wire and the stainless steel workpiece under the confinement of shielding gas. The welding wire fed by the mechanical welding equipment is a welding rod, which is melted into liquid stainless steel under the arc. In view of the versatility and particularity of the MAG welding method, it is the most widely used welding method in the stainless steel welding industry today. And, because of its many advantages, it must be the most widely used welding method for a long time.
Again, tungsten inert gas shielded welding. In this method of use, the arc is generated on a stable tungsten electric welding wire and a stainless steel workpiece. The shielding gas used in this shielded welding is argon, and the welding wire itself fed by the automatic welding equipment is not charged. The welding wire can also be manually Sent, but there is a certain risk. Under some specific conditions, it is not necessary to feed the welding wire, and the stainless steel material to be welded determines whether to use direct current. If the direct current is used, the tungsten welding wire must be set as the negative pole, because its own penetration ability is very strong, and it has a good welding effect on various types of stainless steel.
