Spot welding creates overlapping seams which, when immersed in electroplating solutions, trap solution residues through capillary action. This creates two problems. First, the residue often leaves plating salt deposits which are unsightly and which, in extreme cases, may require touch up or manual removal at increased cost. Second, the metal in the seam is unprotected and can corrode severely in harsh environments. When designing spot welded assemblies for electroplating, consideration must be given to plating drainage, enclosed seams and pockets, overlapping seams and other areas where solutions may be trapped or where special cleaning or processing techniques may be required. When these operations are combined, early consultation with an experienced supplier is crucial.

Start off by drilling 7.5mm holes in the front sheet of metal at a spacing of normally 25mm to 40mm (or whatever the original spot weld spacing was). Then clamp this sheet onto the back sheet. 7.5mm is a reasonably good hole size for 0.8 or 1.0mm sheet. Thicker sheet might require a slightly larger hole size. Try a little test piece out like this one before welding a whole sill onto a car and check the weld has penetrated through both sheets.

Spot welding is a resistance welding process that is used primarily for welding two or more metal sheets together by applying pressure and heat to the weld area. It works by contacting copper alloy electrodes to the sheet surfaces, whereby pressure and electric current are applied and heat is generated by the passage of current through resistive materials such as low carbon steels.

To make sure your welding settings are correct, you should carry out a test run using metal offcuts, followed by a destructive test where you separate the welded parts with a hammer and a forked chisel. After separation, a hole must be made in one of the two conjoined sheets – a process known as “unbuttoning” in metalworking jargon – as proof that the settings are right for the metals and thicknesses involved. Apologies for the abstruse technical term! When welding radiators, make sure you also carry out a leak test.

A few cleaning advices and a high quality recommendation if you are looking for cleaning services in Paris. If you need a quality pet stain or odor removal service that you can count on, then you have come to the right place! Our customers continue to choose us as their carpet cleaning provider because they know that we work diligently to get the job done. Our crew has the knowledge and experience to tackle both pet stain and odor problem issues. Our cleaning solutions are non-toxic to you, your pets and your family. Beware: Pet urine can in fact cause permanent staining on your carpet and upholstery! The urine is initially in a slightly acidic state — it is much easier to clean when fresh and can typically be treated with a “stage 1” topical treatment. Once it dries, it turns alkaline and becomes much more difficult to remove. If left for days, weeks or several months the urine can permanently change the dye structure, causing dye loss or a bleaching effect, which results in permanent staining. Even if the soluble deposits are removed, the damage to the dye structure may already be done.

Vacuum slowly enough to get out as much dirt as possible. Make one quick pass over low-traffic areas and two slow passes over high-traffic areas. Two slow passes removes ground-in dirt more effectively than several fast passes. Use walk-off mats inside and out to keep dirt off the carpeting. Coarse-textured mats outside your doors remove soil and will make a how to clean carpet project easier. Water-absorbent mats inside prevent wet shoes on the carpeting.

La plupart des fabricants de tapis recommandent les professionnels l’extraction de l’eau comme methode de nettoyage principale pour les tapis synthetiques.

Of the five controls tested the enclosing hood, the downdraught bench and the on-tip extraction system are the most effective. Each has advantages and disadvantages in various situations and careful consideration of the processes and tasks to be controlled is required to select between the three. The mobile capturing hood is capable of controlling exposure if used correctly, but like all capturing hoods requires repositioning if the source moves in order to keep it within the effective capturing zone. This means that the potential for worker misuse leading to exposure to solder fume is high, for this reason it should be considered secondary to the other forms of control in the opinion of the author.

The Health and Safety Executive (HSE) are the government body responsible for the regulation and enforcement of work related risks to people in the work place. Dust & fume exposure is a key element of the COSHH 2002 (Control of Substances Hazard to Health) regulations setting out exposure limits, preventative guidelines and on going reductions of the contact between people and hazardous gas and particulates. Under COSHH, companies must take steps to prevent, control, maintain and monitor dust and fume exposure in the workplace, as laid out in regulation 9.

LEV Testing is a legal requirement in the UK for compliance with health and safety standards. LEV Test reports often form part of a company’s insurance policy. Inadequate testing can result in employers being prosecuted, insurance policies being invalidated and even employees becoming ill.

How Welding Supplies Direct can help ? WE will carry out a thorough tests in line with COSHH Regulation 9 as detailed in HSE Guide HSG258 Our levels of service can be tailored to your Companies needs. However, most clients choose to take advantage of by combining servicing with the LEV testing. See more details at https://www.weldingsuppliesdirect.co.uk/welding-equipment/lev-testing.html.

Thousands of British workers contract occupational lung diseases such as occupational asthma and chronic obstructive pulmonary disease each year. Many people die or are permanently disabled by these conditions and are unable to work. People develop these diseases because they breathe in too much dust, fume or other airborne contaminants at work, often because control measures do not work well enough. Most industries are affected, including woodworking, welding, paint-spraying, stonemasonry, engineering and foundry work.
