Welding skills for stainless steel elbows

Welding skills for stainless steel elbows

When customers order stainless steel elbow pipe products in the company, our company will briefly introduce the welding skills of stainless steel elbow pipe products for customers when customers order. Through the simple introduction of the company for customers, customers will reduce the staff in the connection process, so that stainless steel elbow pipe products have a long service life.

In the use of stainless steel elbow pipe, whether heating or cooling, the door should be stainless steel elbow pipe surface and the heart of the cooling speed and time is inconsistent, the formation of temperature difference, which will also lead to volume expansion and contraction of uneven stress, called thermal stress.

Stainless steel elbow under the action of thermal stress, the surface temperature will be lower than the heart, when the end of cooling, the volume shrinkage after cooling can not be free, and then make the surface compression of the heart tension, under the action of heat, make the surface pressure and the heart tension.

This phenomenon is caused by the cooling rate, material composition and heat treatment process, stainless steel elbow hair welding is the use of alternating current skin effect and proximity effect, after the steel roll forming, will travel a section of the circular blank, when the blank near the induction coil center near the time, The impedance device runs an electromagnetic induction circuit with the opening of the tube blank.

Such stainless steel elbow pipe fittings have played an effective role, the edge of the pipe blank opening will produce a concentrated thermal effect, is the welding edge quickly heated, to achieve the temperature needed for welding extrusion, after this operation process welded elbow pipe products firm.
