Melt welding uses heat, plus metal as an additive, to join two surfaces. The most common methods are TIG and MIG. TIG is best suited for thin-walled materials and provides fine weld joints. MIG is used in welding thicker materials, has higher welding speed but poorer finish on the weld joints.
COLD PRESSURE WELDING
Cold press welding joins two aluminum pieces without adding heat or metal to the process. The joint is obtained when the specially designed joint parts of the aluminum pieces are compressed under high pressure and movement. This combines the atoms in the two pieces with a durable joint.
Riveting is carried out as pop riveting or riveting. Pop riveting is the most common method and is performed without countermeasures. Stitch riveting is carried out without the addition of other material and is done with the help of countermeasures.
Soldering is suitable for thin cargo sizes, small details and when joining other metals.
Friction Stir Welding is a welding method where heat is supplied by friction.
Bonding can be similar to soldering or welding but uses plastic instead of metal as an additive. Common types of adhesives are one- and two-component epoxy and polyurethane adhesives. Since there are many different alternative adhesive methods, it is of the utmost importance to carefully consider the best option for each application.
Screw joints are most often used when you want to be able to disassemble the joint. A self-drilling, hot-dip galvanized groove screw is usually used.
