HOBART Brothers Company is a manufacturer of welding filler metals marketed under the brand names Hobart, Tri-Mark, McKay and Corex. The company is a wholly owned subsidiary of Illinois Tool Works, Inc, a multinational manufacturer of a diversified range of value-adding and short lead-time industrial products and equipment. To improve weld quality on modified grade 91 steels used in high-temperature, high-pressure applications in the power generation and petroleum industry, Hobart Brothers offers Tri-Mark ® TM-B9 welding The Tri-Mark TM-B9 welding wire also features a fast freezing slag that allows for welding in all positions without concern for slag inclusions. Low spatter levels and arc stability add to the wire’s ability to produce high quality flat weld beads. The wire offers a tensile strength of 116ksi and yield strength of 96ksi. It is available in 0.045" diameters on 33lb spools, and operates with a shielding gas mixture of 75% argon and 25% CO 2 . Hobart Brothers Company – USA Fax: +1 800 541 6607 Website: www.hobartbrothers.com Low alloy welding for high temperatures wire. This gas-shielded flux-cored wire offers all-position welding capabilities and fully matches the base material properties, ensuring weld quality. The TM-B9 wire meets the requirements of chrome-moly welding, including providing an X-factor of less than 15 parts per million. It also provides a weld deposit with low diffusible hydrogen content – 3.1ml per 100g of weld metal – to prevent cracking during the pre- and post-weld heat treat cycles of grade 91 steels. This feature results in X-ray quality welds and minimises costly downtime for rework.

Forming/roll forming machine

MANCHESTER Tool & Die, Inc has introduced a new, hydraulically operated end forming/roll forming machine, Model M10- H3-R, featuring standard MTD components and using the same tooling as the M71-H-3 and 24008 machines. The M10-H3-R offers the new HMI (human machine interface) user-friendly, programmable flexible control system

and includes diagnostics for machine maintenance. The end and roll forming stations are positioned so the operator can load and unload both clamp areas. A design offering future auto loading and unloading systems allows tube end forms requiring end forming and roll forming processes to be completed without any staging of materials between processes.

The M10 can also be designed with a 6-position end form station for tube end forms that require components to be assembled onto the tube before the rolling processes. Manchester Tool & Die Inc – USA Email: testeffen@mtdtube.com Website: www.manchestertoolanddie.com
