Technology Update
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
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.
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% CO2.

Low alloy welding for high temperatures
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.
