Solderers and Brazers

Tasks

Core Tasks Include:

• Melt and apply solder along adjoining edges of workpieces to solder joints, using soldering irons, gas torches, or electric-ultrasonic equipment.
• Heat soldering irons or workpieces to specified temperatures for soldering, using gas flames or electric current.
• Examine seams for defects and rework defective joints or broken parts.
• Melt and separate brazed or soldered joints to remove and straighten damaged or misaligned components, using hand torches, irons, or furnaces.
• Melt and apply solder to fill holes, indentations, or seams of fabricated metal products, using soldering equipment.
• Clean workpieces to remove dirt or excess acid, using chemical solutions, files, wire brushes, or grinders.

Supplemental Tasks Include:

• Guide torches and rods along joints of workpieces to heat them to brazing temperature, melt braze alloys, and bond workpieces together.
• Adjust electric current and timing cycles of resistance welding machines to heat metals to bonding temperature.
• Clean equipment parts, such as tips of soldering irons, using chemical solutions or cleaning compounds.
• Turn valves to start flow of gases and light flames and adjust valves to obtain desired colors and sizes of flames.
• Brush flux onto joints of workpieces or dip braze rods into flux to prevent oxidation of metal.
• Remove workpieces from fixtures, using tongs, and cool workpieces, using air or water.
• Align and clamp workpieces together, using rules, squares, or hand tools, or position items in fixtures, jigs, or vises.
• Sweat together workpieces coated with solder.
• Smooth soldered areas with alternate strokes of paddles and torches, leaving soldered sections slightly higher than surrounding areas for later filing.
• Remove workpieces from molten solder and hold parts together until color indicates that solder has set.
• Select torch tips, flux, and brazing alloys from data charts or work orders.
• Turn dials to set intensity and duration of ultrasonic impulses, according to work order specifications.
• Dip workpieces into molten solder or place solder strips between seams and heat seams with irons to bond items together.
• Clean joints of workpieces with wire brushes or by dipping them into cleaning solutions.
• Grind, cut, buff, or bend edges of workpieces to be joined to ensure snug fit, using power grinders and hand tools.
• Place solder bars into containers and turn knobs to specified positions to melt solder and regulate its temperature.
• Cut carbon electrodes to specified sizes and shapes, using cutoff saws.
• Connect hoses from torches to regulator valves and cylinders of oxygen and specified gas fuels.
