Stick Welding

Stick welding is an informal term; it can also be known as shielded metal arc welding (SMAW), manual arc metal welding (MMA or MMAW) or flux shielding arc welding. Stick welding uses a flux covered consumable electrode to lay the weld; it is a popular manual arc welding technique.

An electric current supplied by a welding power pack forms an electric arc between the metals being joined and the electrode.  Both the piece and the electrode melt forming a weld pool which subsequently cools forming the joint.  As it is laid the disintegrating flux gives off gasses which act as a shield and it also provides a layer of slag; both of this held seal the weld preventing any atmospheric contamination.

Types of metals you can modify with stick welding

Stick welding is very commonly used for many types of metals for the fabrication of low alloy steel, high alloy steel, cast iron, ductile iron and carbon steel. It can be used to weld non-ferrous materials though this is not routinely done. It can also be used on copper, nickel, their alloys, and aluminum at a push.

 

 

What stick welding is used for

Stick welding is commonly used when erecting steel structures and in most industrial fabrication projects. The method can be carried out for modifying various metal structures such as iron security gates, grilles, railings, beams, structural weldings, fencing, balconies, metal staircases, beds and much more.  One of the big uses of stick welding is when looking to seal larger objects. 

Whilst thickness rarely drops below 1.5mm (and only the most skilled attempt this), stick welding has no upper bound so in theory materials of virtually any thickness can be bound together.  Stick welding can also be used in any position.

 

Benefits of Stick Welding

•    It can be used in all types of weather conditions comes rain, hail, wind or shine.

•    It is inexpensive.

•    Shielding gas in not required which keeps the cost down.

•    Pre-welding cleanup time is reduced as it is not sensitive to paint, dirt, rust, and corrosion.

•    Rods are easily changed for different metals.

•    Ground clamps need not be attached close to the welding point.

 

Cons and limitations

•    It can be a slow process.

•    It can be complicated and needs a confident, experienced tradesman.

•    The slag removal process can be time-consuming.

•    It is tough to use on thinner metals.

•    Excess splatter.

•    The creation of rough surfaces.

•    Increased porosity.

•    Welding rods need to be replaced frequently which can end up being expensive

 

Stick welding is a common technique that is used in many of the welder’s services. However, not all welding works can be completed by stick only. We specialise in a wide verierty of welding methods and can therefore deliver other cost effective solutions like gas or MIG Welding and simillar. will be required to complete your task. For more about other types of welding methods and information in general, this page.
