How to choose gas shielded wire for steel welding?

Whether it is a large production line in the factory or a field processing project involving steel welding, welding personnel are required to use professional welding technology, the use of corresponding reliable welding materials, to connect the steel. Especially in the processing and welding of the steel curtain wall profile in the factory, it is necessary to ensure not only high welding strength, but also beautiful and straight welding joints. Next, let's take a look at how to choose gas shielded welding wire for steel welding?

1. Select the structural steel to be welded

For carbon steel and low alloy high strength steel, gas shielded welding wire satisfying mechanical properties is selected mainly according to the principle of equal strength matching. For heat-resistant steel and weathering steel, the consistency or similarity of the chemical composition of weld metal and base metal is mainly considered to meet the requirements of heat-resistant and corrosion-resistant.

2. According to the quality management requirements of welded parts

The selection of gas shielded welding wire is related to welding conditions, slope shape, shielding gas mixture ratio and other technological conditions. On the premise of ensuring the performance of welded joints, welding materials should be selected to achieve welding efficiency and reduce welding costs.
