The Different Types of Welds and How to Use Them

There are many types of welds, however, these can be broken down into several different categories depending on the welding machine being used and the welding process. When we say weld types, this can actually mean two things. First is the style or position the welder would use during the welding process, the next is the type of material that is being welded, of course, we have different processes such as Arc, Mig, Tig, and gas welding. These welding processes produce the most common types of welds which are fusion welds, which involve melting the metal to be joined. Other types of welds are resistance welds, using heat and pressure to join the metal without melting it.

Other types of welds include brazing, soldering, and adhesive welding. Each type of weld has its own strengths and weaknesses, so it’s important to choose the right type of weld for the job at hand. For example, fusion welds are very strong but require high temperatures to work properly, while resistance welding is much cooler but not as strong. Brazing and soldering are used for joining smaller pieces of metal together, while adhesive welding is often used for plastics and other non-metallic materials. Choosing the right type of weld is an important part of any welding project.

MIG Welds

MIG WeldsMig welds are perhaps the most commonly used. Mig types of welds are created by using an electric arc to heat the metal, which is then joined together using a filler wire. This type of weld is particularly well suited for joining thin sheets of metal, as it produces a strong bond without adding too much bulk. However, Mig welds can also be used on thicker pieces of metal up to 2 inches thick in some cases., making them versatile and adaptable.

Mig welds and MIG welders are probably the most versatile of any welding type. Use on steel, aluminum, and stainless steel, in manufacturing, production work, and for the home workshop.

Mig welds can be performed in different positions depending on the circumstances, this includes down-hand positions, vertical up positions, and vertical down positions.

TIG Welds

tig weldingTig welds are more specific than MIG or arc welding. Best used in precision work and commonly used in the manufacture of food processing equipment and sporting equipment such as mountain bike frames.

Widely used in industry for manufacture, also common as a repair weld in engineering and maintenance. Not so used in home workshops however a common weld used in metal artwork creations.

Braize Welds

oxy acetylene weldingBraize welding is a type of welding that uses high heat to braze two pieces of metal together and is generally performed with an oxy-acetylene torch. The process typically involves heating the two pieces of metal to a temperature that is above the melting point of the filler material but below the melting point of the base metal. This allows the filler material to flow into the joint and form a strong bond between the two pieces of metal. Braize welding is often used to join dissimilar metals, such as copper and steel. It is also commonly used to repair damaged or cracked metal parts, typically cast iron. Braize welders must have a great deal of experience and skill in order to produce high-quality welds.

Braizing is more used in industrial and repair applications

Soldering welds

Soldering is a process in which two or more metal pieces are joined together by melting and flowing a filler metal (solder) into the joint. The filler metal has a lower melting point than the base metal, so it can be melted and drawn into the joint by capillary action. Soldering is usually done at temperatures below 450°C (850°F), and it is used to join metals such as lead, tin, zinc, and aluminum. It can also be used to join dissimilar metals, such as copper and steel. Soldering is distinguished from welding in that the soldered joint is not as strong as a welded joint and it cannot be used on materials that cannot be melted.

The main use of soldering is in the electronics industry, where it is used to connect electronic components to circuit boards. It is also used in plumbing, automotive repair, and jewelry making.

Adhesive Welding

Adhesive welding is a type of welding that uses adhesive to bond two pieces of material together. The adhesive is applied to one or both of the surfaces to be joined and then the two pieces are pressed together. Heat may also be applied to help cure the adhesive and create a stronger bond. Adhesive welding is often used in applications where traditional welding methods cannot be used, such as joining dissimilar materials or joining materials that are sensitive to heat. It can also be used to create structures that are lighter and more delicate than those made with traditional welding methods. Adhesive welding is an important tool for engineers and manufacturers, and it will continue to play a vital role in the future of manufacturing.

Arc or Stick Welds

types of weldsStick welding is one of the most popular and versatile welding processes. Stick welds are strong and can be used on a variety of materials, including metals that are difficult to weld. The process is also relatively simple, making it a good choice for beginner welders. In stick welding, an electrode is used to create an arc between the metal and the electrode. The heat from the arc melts the metal, allowing the two pieces to be joined together. Usually, stick welding is used to join two pieces of metal together. However, it can also be used to repair metal that has been damaged by corrosion or wear. Overall, stick welding is a versatile and popular choice for welders of all levels of experience.

Great for home and farm welding, also extensively used in the fabrication and maintenance industry.

Types of welds positions

If we consider standard arc welding of mild steel, there are four basic positions that can be adopted by the operator, these weld types are determined more by the position the weld is located in and how easy or difficult it is to weld. Here we have the positions of, down hand, overhead, vertical up, and vertical down.

DownHand  Welds

Down-hand welding is the most common welding position and one of the easiest types of welds to master. Use with MIG, TIG, Stick welds, soldering and Braizing.

Vertical up welds

Vertical up welding is one of the more difficult types of welds as are vertical down and overhead welding positions. In this position, the welder holds the electrode vertically and welds from the bottom up. This position is often used for welding pipes and round objects. It is also a good position for welding vertical seams. The main advantage of vertical up welding is that it is easy to see the weld puddle and control the weld pool. However, this position can be difficult to maintain for long periods of time and can lead to fatigue.

Vertical Down welds

Vertical down welding is where the welding is performed from top to bottom. It can be done using stick welders and MIG welders and is usually done on projects where the standard downhand is impossible. The process takes practice as it typically requires a quicker speed of the weld process as gravity takes hold of the weld pool.

Overhead welds

Again the overhead weld can take some expertise to master and only practice and good control will produce results. Best used with stick welders and specific electrodes such as the 7018 electrodes.
