Welding method of stainless steel wire

When welding, we often involve the welding of stainless steel wires. When welding stainless steel wires, we often use gas-shielded welding machines. Whether it is manual welding or automatic welding, gas-shielded welding machines are a magic weapon for welding stainless steel. Let me introduce to you the welding method of stainless steel welded by gas shielded welding machine.

Gas shielded welding machine

The above is the gas-shielded welding machine produced. When we use the gas-shielded welding machine to weld stainless steel, we must consider the base material material, plate thickness, groove shape, joint form, restraint state, ambient temperature and humidity, cleanliness and the above-mentioned The type and diameter of the welding wire (or electrode), welding current, voltage, welding speed, welding sequence, deposition method, gun (or rod) transportation method, etc. are determined by various factors.

In order to slow down the cooling rate of the weldment after welding and prevent cold cracks. In order to eliminate welding residual stress and improve the structure and performance of welded joints. Ensuring welding quality relies on five major control links: people, machines, materials, methods, and environment.

People – operating skills and experience of welders – high performance and stability of welding equipment materials – high quality methods of welding materials – correct welding process regulations and standardized operating conditions – good welding operating environment based on welding tests and welding processes before welding The assessment and formulation of welding process regulations are “regulations” and are important factors in ensuring welding quality.

During fusion welding, the proportion of the melted base metal in the weld metal. During fusion welding, the ratio of weld width to weld thickness on a single pass weld cross section. During fusion welding, the welding gun moves from the right end to the left end of the weldment seam.

The gas protection effect is good and the welding seam is beautiful in shape. To improve the quality of welded joints, we can start from the following methods: correctly select welding materials, adopt reasonable welding process methods, control the fusion ratio, adjust the welding thermal cycle characteristics, use reasonable operating methods and groove design, supplemented by preheating, Interlayer insulation, slow cooling, post-heating and other measures, or post-weld heat treatment methods, etc., can obtain high-quality welded joints.
