Abstract

The invention discloses a titanic-acid stainless steel welding electrode and a manufacturing method thereof. The titanic-acid stainless steel welding electrode comprises a core wire and a coating, wherein the coating comprises the following ingredients in parts by weight: 20-40 parts of rutile, 5-10 parts of marble, 5-10 parts of X-type titanium dioxide, 4-12 parts of fluorite, 10-20 parts of gold feldspar, 2-8 parts of ferrotitanium, 5-10 parts of phlogopite, 8-20 parts of micro-carbon ferrochrome, 0.1-1 part of antimony oxide, 3-10 parts of electrolytic manganese, 2-8 parts of potassium titanate and 3-10 parts of Haitai powder. The titanic-acid stainless steel welding electrode and the manufacturing method have the advantages that the surface tension of a molten drop is reduced, so as to achieve a fine molten drop spraying process; and not only is the welding efficiency improved, is the welding period shortened, and are the tendencies to redness and cracking reduced, but also the technological performance is improved.

Description

technical field [0001] The present disclosure generally relates to the field of welding technology, specifically to the field of welding rods, and in particular to a titanate-type stainless steel welding rod and a manufacturing method thereof. Background technique [0002] Stainless steel electrodes can be divided into chromium stainless steel electrodes and chrome-nickel stainless steel electrodes. Those of these two types of electrodes that meet the national standard shall be assessed according to the national standard GB / T983-1995. Chromium stainless steel has certain corrosion resistance (oxidizing acid, organic acid, cavitation) heat resistance and corrosion resistance. It is usually selected as equipment material for power station, chemical industry, petroleum and so on. However, the weldability of chromium stainless steel is generally poor, and attention should be paid to welding process, heat treatment conditions and selection of suitable welding electrodes. Chromi...
