Study Notes

General Welding Information

  • Welding is a localized coalescence of metals.
  • Heat is used to fuse the metals, possibly with filler metal.
  • The weldment is as strong as the parent metal.

Extrusion

  • Extrusion ratio is the ratio of billet to product cross-sectional area.
  • Hot extrusion ratio can be up to 400:1 (aluminum)
  • Hydraulic or mechanical presses are used for extrusion
  • High pressure (400 atm) is common
  • Lubricants reduce friction
  • Extrusion speed varies from 0.5 m/s for light alloys to 4.5 m/s for copper alloys.

Cold Extrusion

  • Cold extrusion is similar to hot extrusion, but no heating is needed.
  • High metal ductility is helpful
  • Used to improve physical properties, size a part.
  • The Hooker method, impact extrusion, and hydrostatic extrusion are common methods.
  • Hooker method uses a punch with a shoulder acting as a mandrel and pushes the metal through.
  • Impact extrusion is fast, uses a powerful punch blow and is used for thin-walled tubes
  • Hydrostatic extrusion uses high pressure liquid to force metal through die.

Advantages of Extrusion

  • Wide variety of extruded objects possible
  • Easily interchangeable dies
  • High dimensional accuracy
  • Improved ductility, especially for metals that do not deform easily
  • High reduction ratios are possible
  • Quicker automation, single passing
  • Creating smaller parts in large quantity
  • Stronger and lighter than other production methods like castings

Disadvantages of Extrusion

  • Higher waste percentage than other forms of shaping
  • More inhomogeneous structure than other methods due to different flows
  • Short tooling life due to high stresses from operation
  • High tooling costs
  • Low productivity compared to methods like rolling
  • Only constant cross-sectioned products are possible

Other Extrusion Processes

  • Side Extrusion (Lateral Extrusion) involves material flow perpendicular to ram motion
  • Continuous Extrusion - continuous feedstock and pressure applied to the back to create a continuous product
  • Conform process - continuous feedstock in a rod form.

Pipe and Tube Manufacturing

  • Pipes and tubes can be seamless or with seams.
  • Seamless tubes are made by extrusion and piercing
  • Continuous seam welding is used for pipes.
  • Piercing Method creates thick-walled shells in a rolling mill
  • Rolling of the shell into the desired pipe shape

Welding Process

  • General Definition: Localized coalescence of metals using heat, possibly filler material, and pressure
  • Welding Applications: Wide variety of applications across industries (structural steel, pressure vessels, pipelines, and automobiles) for fabrication and repair of metal components, including machinery frames, parts, and fixing panels.
  • Welding Advantages: Economical, reliable, high adaptability to shapes and sizes, repair of defective metals.
  • Welding Disadvantages: Less readily machinable compared to castings, and issues of weld defects like cracks, inclusions, porosity.

Classification of Welding Processes

  • Pressure Processes (e.g., forge welding, thermit welding, pressure gas welding, electric resistance welding)
  • Fusion Processes (e.g., gas welding, electric arc welding, thermit fusion welding)
  • Autogenous welding does not use filler material.
  • Homogeneous welding means filler metal is the same as the parent metal.
  • Heterogeneous welding means filler metal is different. Brazing and Soldering are examples, however not strictly welding processes as per some definition

Other Welding Processes

  • Gas Welding: Uses a gas flame to melt the metal and filler material if used for joining
  • Electric Arc Welding: Uses an electric arc to melt the metal and filler metal for joining
  • Thermit Welding: Uses a chemical reaction to melt metal and filler material together, high temperature and possible for thick pieces
  • Continuous Furnace Butt-Welding; process uses to manufacture water and gas pipes.
  • Electric Resistance Welding: Uses heat from resistance to electrical current in order to create a weld (spot welding is a type of resistance welding)
  • Induction Welding: Heat developed by resistance to the induced electric current is used. Suitable for low conductivity materials
  • Friction Welding: Heat is generated from rubbing metallic parts together, and these parts are then pressed together under force to create a weld.
  • Ultrasonic Welding: Ultra sonic vibrations cause welding to occur based on the use of high frequency vibrations to produce heat without the use of filler metal
  • Explosive Welding: Explosives are used to cause heat and pressure in order to weld materials together
  • Flow Welding: Adds molten filler metal to the joint
  • Cold Welding: Uses pressure without heat
  • Plasma Arc Welding: Used for welding materials that have high refractory properties, or for high-precision work,
  • Stud Welding: Arc welding is used to create welds in studs (fasteners)
