Solderers and Brazers

Guide torches and rods along joints of workpieces to heat them to brazing temperature, melt braze alloys, and bond workpieces together.

Turn valves to start flow of gases and light flames and adjust valves to obtain desired colors and sizes of flames.

Adjust electric current and timing cycles of resistance welding machines to heat metals to bonding temperature.

Examine seams for defects and rework defective joints or broken parts.

Align and clamp workpieces together, using rules, squares, or hand tools, or position items in fixtures, jigs, or vises.

Melt and apply solder to fill holes, indentations, or seams of fabricated metal products, using soldering equipment.

Melt and apply solder along adjoining edges of workpieces to solder joints, using soldering irons, gas torches, or electric-ultrasonic equipment.

Clean workpieces to remove dirt or excess acid, using chemical solutions, files, wire brushes, or grinders.

Heat soldering irons or workpieces to specified temperatures for soldering, using gas flames or electric current.

Grind, cut, buff, or bend edges of workpieces to be joined to ensure snug fit, using power grinders and hand tools.

Brush flux onto joints of workpieces or dip braze rods into flux to prevent oxidation of metal.

Smooth soldered areas with alternate strokes of paddles and torches, leaving soldered sections slightly higher than surrounding areas for later filing.

Melt and separate brazed or soldered joints to remove and straighten damaged or misaligned components, using hand torches, irons, or furnaces.

Clean joints of workpieces with wire brushes or by dipping them into cleaning solutions.

Remove workpieces from fixtures, using tongs, and cool workpieces, using air or water.

Connect hoses from torches to regulator valves and cylinders of oxygen and specified gas fuels.

Sweat together workpieces coated with solder.

Dip workpieces into molten solder or place solder strips between seams and heat seams with irons to bond items together.

Place solder bars into containers and turn knobs to specified positions to melt solder and regulate its temperature.

Turn dials to set intensity and duration of ultrasonic impulses, according to work order specifications.

Select torch tips, flux, and brazing alloys from data charts or work orders.

Cut carbon electrodes to specified sizes and shapes, using cutoff saws.

Clean equipment parts, such as tips of soldering irons, using chemical solutions or cleaning compounds.

Remove workpieces from molten solder and hold parts together until color indicates that solder has set.
