Stainless steel welding is a complex mixture of metallurgy, chemistry, geometry and aesthetics. The welds properties, e.g. corrosion resistance, have to be correct and the right surface finish has to be achieved.
If the gap is too small, the proximity effect is increased, the welding heat is too large, and the weld is burnt; or the weld is pressed and rolled to form a deep pit, which affects the surface quality of the weld. Low carbon steel material, welding temperature is controlled at 1250~1460 °C, which can meet the welding requirements of pipe wall Building Material Square Galvanized Profile Hollow Steel Square Galvanized Pipe, Square Pipe, Galvanized Pipe manufacturer / supplier in China, offering Building Material Square Galvanized Profile Hollow Steel Pipe Shs Rhs Weld Steel Tube, Hot Rolled Steel Plate Nm400 Nm450 Nm500 Anti Wear Plate Hardox Steel Plate, Welded Pipe Welded Steel Tube Welded Square Tubes and so on.

100 million tons of steel prod-ucts a year, making the ability to weld steel economically and achieve good properties in the fabricated structure key to its prevalence in man-ufacturing. The purpose of this article is to shed light on the fact that AWS D1.1 Structural Welding Code Steel, does not currently include cast carbon steel How to weld Duplex Stainless Steel.ppt [Read-Only]Duplex Stainless Steel Mechanical properties Duplex steels are characterized by high strength. High strength also means that fatigue properties are very good. However, fatigue strength is dependent on:The components design shape. The welded joint itself. The welding method and joint type are also of great significance. Example:

Substitution of A36, SS400 and Q235 steel plate Although the Q235 steel grade steel plate has lower mechanical properties than A36 and SS400 material, but in actual operation process, as long as the buyers do not have special requirement, often these three kinds of materials can be substituted.
- Q235 SteelFeatures and ApplicationsData Sheet and SpecificationQ235 Steel EquivalentQ235 steel is a plain carbon structural steel which is widely used in China, Q235 material in Chinese standard GB/T 700 is divided into 4 quality grades:Q235A, Q235B, Q235C and Q235D; Density of this steel is 7.85 g/cm3, tensile strength is 370-500 MPa; yield strength is 235 MPa (data are for steel bar or steel plate diameter 16mm). Since its mild steel, it is used directly without heat treatment.(PDF) Microstructure and mechanical properties of Q235 Microstructure and mechanical properties of Q235 steel welded joint in pulsed and un-pulsed ultrasonic assisted gas tungsten arc welding July 2019 Journal of Materials Processing Technology 275:116335

Spiral Weld Pipe. Spiral Weld Pipe, as the name implies, is a steel pipe that has a seam running its entire length in a spiral form. In the past, due to the method of manufacture, Spiral Welded pipe was relegated to low pressure and structural applications. What is difference between seamless and welded pipe? Welding of austenitic stainless steels for cryogenic LNG Before setting up the requirements for LNG weldments the general mechanical properties of the austenitic steel and the main influences on the achieved test data have to be discussed. 2 Strength properties austenitic steels for LNG application Strength design is primarily done using room temperature properties. The all weld metal
