Welding comes in many forms and is used across a variety of industries. When used, welding serves to offer a secure join across two or more metal components.

There are many different types of welding and, here at Grenville Engineering, we offer the most common and preferred methods. More specifically, we specialise in MIG and TIG welding, while also being ASME 9 compliant. We are experienced in a range of ferrous and non-ferrous metals.

Welding refers to a process of joining metal materials. This is achieved via fusion. During welding, the metal is melted and some additional molten material is introduced so that, when cooled, a strong joint occurs.

The benefit of this is that this fusion does not simply connect the two pieces. Instead, they are fused together and act like one component. This ensures they stay firm and rigid, helping in a wide range of applications.

Because of its many uses, welding is used in various industries. Motor vehicles and the aviation industry, for example, both use welding to securely attach sections of their crafts. Similarly, manufacturers and even infrastructure, such as tower buildings, all use welding to securely attach metal sections without sacrificing strength or durability.

MIG stands for “metal inert gas” and refers to a type of welding which uses a wire electrode and arc to weld metal together. To keep the welding area free from contaminating particles, a ‘shielding gas’ is used to keep it clean and this is where MIG draws its name from. Additionally, MIG uses a continuously feeding wire, allowing for consistent welding.

One of the biggest benefits to MIG welding is that it is quick and allows for a high quality weld. The gas shield also ensures that very little of the alloying material is lost, creating a strong weld as a result.

TIG stands for “tungsten inert gas” and refers to an alternative method for welding. It is named after the Tungsten electrode used. Unlike MIG, TIG involves of long welding rods, which need to be fed into the puddle to complete the weld.

This method is often used when control and finesse are required. TIG welding can also be completed on lower power settings, which is highly advantageous when working on thinner components, as it greatly reduces the risk of burning through the material.

ASME 9 is an American qualification that is typically used as an internationally recognised code or standard. More specifically, it refers to pipe joints and is often used alongside boilers, valves and pressure related systems.

One of the big benefits to ASME 9 is that it is a widely recognised and used standard, designed to be compliant and compatible with other ASME standards. This ensures that coded welding is often the safest and most trusted option when welding with ASME.
