Friction welding solutions for the Oil and Gas industry
Friction welding’s proven reliability is coupled with such process advantages as being clean, fast, consistent, and free of operator-induced error. This makes friction welding one of the leading methods of joining flanges to valve bodies, drill pipe, high-pressure hose couplings, and manifold tubes.
Harbison-Fischer, a manufacturer of oil well pumping equipment, was having trouble producing a key pump part in a timely and cost-efficient manner. After teaming up with MTI, we applied our partnership process along with our experience in oil field applications.
This led to developing a friction welding machine that solved their problem by manufacturing the part with much higher quality while also saving them time and money. The experience also resulted in creating other innovations for this and other industries as well.

Since a typical string of drill pipe can be three to four miles long, composed of 30-foot sections, weld integrity is a must in the oil field drilling industry. The friction welds support the lower drill stem assembly (made up of other drill pipes, drill collars, and the drilling bit) and transmit the rotary torque needed for drilling. Friction welding produces a metallurgical bond strong enough to take the high torque and highly loaded rotary tension due to directional drilling.
