Manual Metal Arc Welding (MMA)

Arc welding, sometimes called manual metal arc welding (MMA), is a method for binding metal to metal by using electricity to create enough heat to melt the metals; when cooling down, the metals bind to one another. This method uses a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. Though it is not suitable for pipe welding, it can be used for fabrication of steel structures.


Gas metal arc welding, also referred to as metal inert gas welding (MIG) or metal active gas welding (MAG), is a welding process in which an electric arc forms between a consumable wire electrode and workpiece metal(s), which then heats the workpiece metal(s), causing them to melt and join. For MIG welding, the inert gas used is usually argon, helium or some mixture thereof. For MAG welding, CO2 is used, which reacts in the molten weld pool with the fusion joint. Along with the wire electrode, a shielding gas feeds through the welding gun, which shields the process from contaminants in the air. The advantage of these methods is faster welding and less slag.

Flame welding (oxy-fuel welding)

Oxy-fuel welding (commonly called gas welding in the U.S.) and oxy-fuel cutting, are processes that use fuel gases and oxygen to weld and cut metals. A welding torch is used to weld metals by heating two pieces to a temperature that produces a shared pool of molten metal. Additional metal called filler is generally added to the molten pool (filler material depends on the metals to be welded). Oxy-fuel is one of the oldest welding processes, yet in recent decades almost all industrial uses have become obsolete due to the spread of various arc welding methods that offer more consistent mechanical weld properties and faster application. In oxy-fuel cutting, a torch is used to heat metal to its kindling temperature. A stream of oxygen is then trained on the metal, burning it into a metal oxide that flows out as slag.


Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce a weld. The weld area and electrode are protected from oxidation and other atmospheric contamination by an inert shielding gas (argon, helium or a mixture thereof) and a filler metal.

A constant-current welding power supply produces electrical energy, which is conducted across the arc through a column of highly ionized gas and metal vapours known as a plasma.

GTAW is most commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminium, magnesium and copper alloys. The process grants the operator greater control over the weld than competing processes such as shielded metal arc welding and gas metal arc welding, allowing for stronger, higher-quality welds. However, GTAW is comparatively more complex and difficult to master, and therefore significantly slower than most other welding techniques.

Welding certifications

Our welders are certified in accordance with EN 9606, as well as the older EN 287. Welders involved in manufacture/installation/repair of equipment that falls within the scope of the Pressure Equipment Directive (PED) must be approved by a competent third party in accordance with Czech and EN directives. Welding
Procedure Qualification Reports (WPQR) and Welding Procedure Specifications (WPS) are always issued by a qualified EWT (European Welding Technologist).
We can also submit any such documentation to local certifying agencies in English, German and French.
