Abstract

The invention discloses a welding rod coating for steel. The welding rod coating is prepared by following raw materials including 16-19 parts of potassium carbonate, 10-12 parts of kaolin, 10-13 partsof titanium dioxide, 12-16 parts of feldspar, 6-8 parts of white mud, 6-8 parts of starch and 3-4 parts of iron powder. By means of the welding rod coating, cracking can be effectively prevented, during welding, electric arcs are stable, splashing is little, the welding quality is guaranteed, the welding face is flat and smooth, and slag disengaging is easy after welding.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an electrode coating for steel. Background technique [0002] Welding: also known as welding and welding, is a manufacturing process and technology for joining metal or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. As an important material processing technology, welding is widely used in petrochemical, electric power, aerospace, power engineering, microelectronics technology, bridges, ships and various metal structures and other industrial sectors. The coating of the existing electrode is seriously cracked, which affects the quality of welding, which puts forward higher requirements for steel products with strict welding requirements. Contents of the invention [0003] In order to solve the above existing problems, the present invention provides an electrode coating for steel that can effectively prevent cracking, has a...
