We are proud to be stockists of welding consumablesand suppliers of many recognisable, reputable brands. We stock welding machines for different welding processes, some of our machines are multi-process to increase their versatility and value for money. With over 30 year's experience in the industry, we are proud to be supplying to experienced domestic user, and the construction trade users across Coventry, Rugby, Oxford and the surrounding areas.
Before you start any welding process, it's important to make sure you have the correct welding equipment, including but not limited to fire-resistant jacket, safety glasses, welding gloves and the most important of all, an approved welding helmet. Since their initial development, welding helmets have developed dramatically with extra safety features. It's easiest to look for an auto darkening helmet to protect your eyes from the bright flare and sparks of the welding process. Adequate ventilation, such as a fume extraction system, is recommended. Because of the sparks, make sure there are no flammable materials on or around the welding work; choose a location that will give you plenty of room to let the sparks fly.
Choosing a Welding Machine
The most common welding processes are MIG, TIG and Stick. Each process has it's benefits and limitations, meaning there's no "one-size-fits-all" process, they are each suited to their individual circumstances. Matching your needs and welding skills to the application and the welding process is important before choosing a specific model of welding machine.
As an example, you can weld aluminium with the MIG process, but you will get better results if you use a spool gun to feed the consumable rather than a wire feeder. Guidance from the manufacturer and/or the retailer about these details can help you make the decision in which welder to purchase. It's important to also consider the other welding projects you have planned- what metal will you be welding the most? What thickness will these metals be? Where will you be welding them? All these can contribute to the decidion of choosing the welder.
The flux is an important consumable in the welding process. Whether it's in an electrode coating or in granular form, or in a aubmerged arc flux, the requirements are the same. Davies Industrial & Welding Supplies has a large variety of fluxes in many forms, if you don't see a product you wnat, please get in touch and we will try our best to source it for you.
The basic purpose of the flux is to provide a protective shield to prevent any atmospheric contamination to the electrode tip, the filler metal as it's transferred across the arc and the weld pool. Generally, it's achieved by decomposing the heat of the arc to form a protective gaseous shield.
As the most basic requirements, the flux should be able to:
- Removing any oxide film (failure to do so will result in oxide entrapment and damage the integrity of the weld), it must be able to react chemically with the oxide.
- Provide the desired weld metal composition, by transferring alloying elements across the arc
- Produce a slag which will shape the weld pool and if required, hold the pool in place in positional welding.
- Not produce large amounts of fume and, and any fume it produces should not be harmful to the welder.
