The Types of Flux-cored Welding Wire

Flux-cored welding wire is more and more popular in engineering practice because of its lower comprehensive cost, faster deposition speed and less splash. According to the manufacturing process, it can be divided into seam flux-cored wire and seamless flux-cored wire. Seam flux-cored wire is a thin steel strip processed into grooves by forming rollers, involved in powder to roll into a tube […]

Tips of welding Austenitic stainless steel

Austenitic stainless steel is the most widely used type of stainless steel, mainly Cr18-Ni8, Cr25-Ni20, Cr25-Ni35 type. The welding of austenitic stainless steel has obvious characteristics: Welding hot crack. Austenitic stainless steel is easy to form a bulky columnar grain structure when the welding joint parts of high temperature and retention time is longer because of small thermal […]
