Forging technology for high-strength welding wire

Abstract

The invention belongs to the field of welding wires and relates to a forging technology for a high-strength welding wire, in particular to the high-strength welding wires and application of the high-strength welding wires. The high-strength welding wire comprises important metal elements and important alloy elements. The forging temperature range meets preset initial forging temperature and final forging temperature. The forging temperature can be set to guarantee that metal is high in plasticity and small in resistance to deformation within the forging temperature range, and structure and performance temperature values are obtained. Therefore, the quality of a forged blank meets the quality of a follow-up finished product better, and positive effects are directly generated on material forgeability and the structure and performance of the forge piece.

Description

technical field [0001] The invention belongs to the field of welding wire, in particular to high-strength welding wire and its technology. Background technique [0002] The research of high-strength welding wire is based on ordinary stainless steel welding wire, and the research and development of welding wire products with higher tensile strength and higher tensile strength of deposited metal. It is mainly used for welding of heavy and large vehicles. Since the mechanical properties of ordinary stainless steel welding wire and the mechanical properties of deposited metal cannot meet the increasing welding requirements of high-strength steel, a new type of welding for heavy and large special vehicles is invented. High-strength welding wire, which is based on the existing stainless steel wire with an appropriate amount of certain ingredients, and at the same time correspondingly increases the content of special ingredients. However, the change of the alloy composition of the...

It is mainly used for welding of heavy and large vehicles. Since the mechanical properties of ordinary stainless steel welding wire and the mechanical properties of deposited metal cannot meet the increasing welding requirements of high-strength steel, a new type of welding for heavy and large special vehicles is invented. High-strength welding wire, which is based on the existing stainless steel wire with an appropriate amount of certain ingredients, and at the same time correspondingly increases the content of special ingredients

However, the change of the alloy composition of the welding wire brings certain difficulties to the later production, which reduces the plasticity and toughness of the alloy steel.
