Welding of relaxation-resistant steel
Buy in any quantity and assortment of relaxation and high-temperature resistant steel at prices from the manufacturer, the company offers Electrocentury-steel. The supplier provides timely delivery of the products to the address indicated by the customer.
Features of welding of these steels
The most widespread purpose of obtaining permanent joints relaxation resistant and heat resistant steels have tungsten arc welding with non-consumable electrode (TIG method) under argon or — at least — helium. In terms of mass and volume production is used for mechanized TIG welding.
The bulk relaxation resistant and heat resistant steels are weldable. Specifically, the weld type is set taking into account dimensions and the structural complexity of the welded products. To improve the corrosion resistance of connections in the zone of the weld filler wire is used, which has titanium.
Welded joints made in view of the above characteristics, resistant against all types of corrosion, as well as from the harmful effects of chemically aggressive liquid media, and retain their performance at temperatures up to 700…7500 C.
The company Electrocentury-steel offers to buy and relaxation of high-temperature resistant steel at favorable prices from the manufacturer. The supplier provides timely delivery of the products to the address specified by the consumer.
Technological modes of welding
When performing welding in argon (compared to similar technologies, is used as the protective gas helium) necessary to implement the increased values of welding current and reduce the arc voltage. Shielding gas flow while decreasing.
Optimal regimes of butt welding of workpieces of relaxation and high-temperature resistant steels with a maximum thickness of 3 mm are:
the welding current is 120…160 A;
arc voltage 12…15 V;
shielding gas flow 6…9 l/min.
When welding heat-resistant steel relaxation any brand, there is a risk of occurrence of macro — and micro-cracks and local discontinuities in the zone of the weld. Therefore, in many cases, the welding conditions are specified empirically. Welding is done only after the hardening products. If it is technologically impossible, the annealing is performed after welding, using heating to a temperature of 1060…1200°C, followed by rapid cooling.
To purchase affordable and high-temperature resistant steel relaxation is offered by the company Electrocentury-steel. Supplier guaranteed prompt delivery of metal in any point set by the user.
