названия профессий

[Л4]

Здравствуйте!
Посоветуйте, пожалуйста, как лучше перевести названия этих профессий:
1) газоэлектросварщик (gas-electric welder?),
2) слесарь строительный,
3) асфальтобетонщик

Спасибо

Электрический сварщик — это стильно! :-)
Welders and Cutters
• Welds metal parts or components together, using brazing, gas, or arc welding equipment.
• Repairs broken or cracked parts, fills holes and increases size of metal parts, using welding equipment.
• Welds in flat, horizontal, vertical, or overhead position.
• Cleans or degreases parts, using wire brush, portable grinder, or chemical bath.
• Inspects finished workpiece for conformance to specifications.
• Chips or grinds off excess weld, slag, or spatter, using hand scraper or power chipper, portable grinder, or arc-cutting equipment.
• Positions workpieces and clamps together or assembles in jigs or fixtures.
• Preheats workpiece, using hand torch or heating furnace.
• Ignites torch or starts power supply and strikes arc.
• Reviews layouts, blueprints, diagrams, or work orders in preparation for welding or cutting metal components.
• Selects and inserts electrode or gas nozzle into holder and connects hoses and cables to obtain gas or specified amperage, voltage, or polarity.
• Connects and turns regulator valves to activate and adjust gas flow and pressure to obtain desired flame.
• Selects and installs torch, torch tip, filler rod, and flux, according to welding chart specifications or type and thickness of metal.
• Guides electrodes or torch along weld line at specified speed and angle to weld, melt, cut, or trim metal.

Fitter, Structural Metal-Precision
• Aligns parts, using jack, turnbuckles, wedges, drift pins, pry bars, and hammer.
• Moves parts into position, manually or by hoist or crane.
• Marks reference points onto floor or face block and transposes them to workpiece, using measuring devices, squares, chalk, and soapstone.
• Gives directions to welder to build up low spots or short pieces with weld.
• Heattreats parts with acetylene torch.
• Straightens warped or bent parts, using sledge, hand torch, straightening press, or bulldozer.
• Locates reference points, using transit, and erects ladders and scaffolding to fit together large assemblies.
• Removes high spots and cuts bevels, using hand files, portable grinders, and cutting torch.
• Sets up face block, jigs and fixtures.
• Examines blueprints and plans sequence of operation, applying knowledge of geometry, effects of heat, weld shrinkage, machining, and metal thickness.

Асфальтобетонщика Вам, наверное, придётся комбинировать:
ASPHALT-PAVING-MACHINE OPERATOR
Operates machine that spreads and levels hot-mix bituminous paving material on subgrade of highways and streets: Bolts extensions to screed to adjust width, using wrenches. Lights burners to heat screed. Starts engine and controls paving machine to push dump truck and maintain constant flow of asphalt into hopper. Observes distribution of paving material along screed and controls direction of screed to eliminate voids at curbs and joints. Turns valves to regulate temperature of asphalt flowing from hopper when asphalt begins to harden on screed.
CONCRETE-PAVING-MACHINE OPERATOR
Operates concrete paving machine to spread and smooth freshly poured concrete surfaces for concrete roads and landing fields: Starts machine, engages clutch, and shifts gears to control machine's movement along rails on concrete forms. Moves levers and turns handwheels to lower attachment that spreads wet concrete within forms. Observes surface of concrete to point out low spots for workers to add concrete. Operates machine with attachments to successively vibrate, screed, strike-off (remove excess from), and float surface of concrete, to spray on curing compound, and cut expansion joints. When cutting expansion joints, places strips of material, such as cork, asphalt, or steel, in joints, or places roll of expansion-joint material on machine that automatically inserts material into joints. When operating machine to screed and float surface, may be designated Concrete-Finishing-Machine Operator (construction). May be designated according to specific function of machine attachment as Center-Line-Cutter Operator (construction); Curing-Machine Operator (construction); Gang-Vibrator Operator (construction); Joint-Machine Operator (construction); Longitudinal-Float Operator (construction). May be designated: Screed Operator (construction); Spreader Operator (construction); Strike-Off-Machine Operator (construction); Vibrating-Screed Operator (construction).
