a. Tack welding . b. Welding secondary members . c. Welding connection plates to rolled beam girders. d. Other short, difficult to access or out of position welds. 7. May be used as an automatic process, except the following must be considered:a. high intensity of arc rays. b. excess amount of smoke. 8. Evaluation of strength and microstructure of welded pipes Jan 12, 2021 · When welding the defect free pipes metal hardness in the fusion zone is insignificantly higher than that of the base metal with consideration to the measurement accuracy. Average values of microhardness for the weld, HAZ and base metal are 174, 167 and 162 HV0.3/10 accordingly.

High Strength Steels - Industeel

Amstrong® Ultra 960 is a quenched and tempered steel for structure with very high strength. Weight saving:Thanks to its minimum yield strength of 960 MPa, Amstrong® Ultra 960 enables large weight savings or support higher stresses and thus carry higher payloads. Cost efficiency:By using Amstrong® Ultra 960 and thus thinner plates in welded INVAR 36 - Rolled Alloys, Inc.INVAR 36 is a nickel-iron, low-expansion alloy containing 36% nickel. It maintains nearly constant dimensions over the range of normal atmospheric temperatures, and has a low coefficient of expansion from cryogenic temperatures to about 500°F. The alloy also retains good strength and toughness at cryogenic temperatures. INVAR 36 can be hot and Industrial Grade Cements & Primers Specification - WELD-ON is the only manufacturer to offer FREE joint failure analysis. For proper solvent welding of pipe and fittings, Professional grade, high-strength, chemical-resistant solvent cement for use with CPVC and PVC piping systems carrying acids, bases, salts, and hypochlorites.

It also enables TIG welding of pipe or tube without the need to stop and change positions in order to weld the entire circumference, as in manual welding.
