Types of Metal Joining Methods

Metalworking allows the production of equipment parts, large structures and individual products. This fabrication sector is particularly important in the manufacture of custom goods such as engine parts, building components, tools and even craft jewellery. The metalwork encompasses a combination of techniques, tools and designs to create durable and functional products.

One of the essential processes in the industry is metal joining which involves linking separate modules or components to form a large complex structure. This can help you simplify the process of making an intricate product because simple parts can be fabricated and connected later. If you are thinking about ordering custom metal items, here are the main metal joining methods that you should inquire about.

Welding

Welding is one of the most popular metal joining processes in custom fabrication. The technique involves bonding the metal components or pieces into a continuous whole.

In simple terms, the work pieces are heated in the parts to be amalgamated to the point of melting. The liquefied sections are brought together and allowed to cool while joined to create a strong, solid joint. In some cases, pressure is applied on the joint before the weld solidifies for a firmer connection.

There are different suitable sources of heat during the joining process, so you should ask your fabricator for a recommendation. Traditional choices include gas flames and electric arc, while precise modern options include laser, ultrasound and electron beams.

Riveting

The popularity of rivets has declined significantly over the years, but the fasteners are still valuable.

Generally, a rivet consists of an unthreaded shaft, a flat head and a tail which is hammered flat to fasten after installation. This fastener is used in metalworking to hold two pieces of metal components together. The metal joining process will require the drilling of holes which will then be aligned to accommodate the rivet.

The use of rivets has been superseded by advanced welding and brazing techniques in most metalworking applications. However, if you want a metal joining method which is semi-permanent, riveting is the right choice. You can remove the rivets if necessary for maintenance and modifications.

Soldering

Soldering is used in diverse metal fabrication applications, including the making of plumbing fixtures, electronic components, machine components and jewellery.

The soldering technique involves joining metal parts by melting filler metal and allowing it to flow into the joint. As the liquefied solder solidifies, it creates a strong bond between the adjoining pieces. This procedure is different from welding because the work pieces should not be melted when soldering.
