MIG Brazing Wires
Engineer Advice
Paul Jones says
MIG brazing wires are essential for bodyshops and repair centres working with a range of materials, particularly aluminium. In a workshop setting, they're primarily used for joining metal sections while minimising heat input, which is crucial when working on components where warping could compromise structural integrity.
When using these wires, proper setup is vital. MIG braze wires are softer than steel so feeding it though a steel liner can prove troublesome unless you have a straight torch when welding. carbon liners are best.
A common issue I've encountered is the tendency for welders to not understand that MIG brazing is a bonding process and therfeore requires surface area of weld to give it its strength. Producing a weld then grinding it down reduces its strength and weld integrity, which can lead to weld failure later on.
In conclusion, when used correctly, MIG brazing wires can provide reliable, strong joints that withstand the rigours of daily use in professional applications. Regular training and adherence to best practices will ensure efficiency and durability in repairs.
