About us

Kehui technology was organized in 1996, as the leading company in the welding and heat treatment field. It concentrates on providing solution and recommendation to clients, hence, we attempt to customize our product relates to clients’ requirements. By the rich experience in such area, we may design and produce various type of product, such as tube-tube and tube-tube sheet, and other type automatic welding machine which successfully be used in petrochemical, manufacturing and boiler industry.

Brief

This welding head is one special designed TIG welding head for tube to tube-sheet, which is used for carbon steel, stainless steel, mainly for flush tube connection without wire feeding.

Application

Applicable industries:petrochemical, boiler, pressure vessel, shipbuilding, food machinery, etc.

Applicable products: pressure vessel, boiler, heat exchanger, etc.

Suitable for: the pipe outer diameter12mm-89mm of carbon steel, stainless steel, copper alloy, titanium alloy, etc.

Feature

>Widely used in power plant/condenser stainless steel/titanium alloy tube to tube-sheet welding;

>With wire feeding, small size and light, easy for operation;

>Expandable collet positioning design, precise position;

>Closed welding achieving perfect welding quality;

>Enhanced water cooling system, high duty cycle for long time using.

Apply:stainless steel,carbon steel,mild steel,copper,etc.
