Abstract

The invention discloses a stainless steel welding rod containing rare earth and carbon steel core and a preparation method thereof, comprising a coating and a welding core, the welding core is covered by the coating; the coating includes the following components, the mass The components in percentage are: 6-12% of marble, 3-8% of fluorite, 1-3% of titanium dioxide, 10-20% of rutile, 1-3% of mica, 3-6% of ordinary potassium feldspar, electrolytic Manganese 3-6%, micro-carbon ferrochrome 20-30%, metal chromium 25-35%, nickel powder 8-12%, rare earth fluoride 0.5-1.5%, rare earth ferrosilicon 1-3%, calcium solvent 0.5-1.5% %, soda ash 0.5-1.0%, sodium alginate 0.5-1.0%. In the present invention, the welding rod is designed in the way of alloyed coating and special carbon steel welding core, which effectively solves the problems that the welding core is easily reddened and the coating is easy to fall off when the large-diameter electrode is welded under the condition of super high current, and has oxidation resistance, Resistance to sulfuration, corrosion and cracking.

Description

technical field [0001] The invention relates to the field of welding materials, in particular to a stainless steel electrode containing rare earth and carbon steel core and a preparation method thereof. Background technique [0002] Magnesium and magnesium alloys are the most promising light metals in the 21st century, widely used in various industries such as auto parts, aerospace, electronics, precision machinery, and military. Due to the expansion of magnesium and its alloys in many fields, since the 1990s, the global consumption of magnesium has maintained an annual growth rate of more than 20% for 10 consecutive years, the production of magnesium is increasing day by day, and the production technology of magnesium has been widely used develop. The methods of producing metal magnesium mainly include thermal reduction method and electrolysis method. More than 80% of metal magnesium in developed countries is produced by electrolysis method. In my country, thermal reductio...
