Welding near you

HSE's safety alert STSU1-2019, issued in February 2019, is the document that changed this trade. It followed the International Agency for Research on Cancer's finding that exposure to mild steel welding fume can cause lung cancer and possibly kidney cancer in humans, endorsed by the Workplace Health Expert Committee. HSE's own guidance now describes all welding fume as being classified in Group 1, the highest carcinogen classification.

The enforcement consequence is stated plainly in the alert: there is no known level of safe exposure, and HSE will no longer accept any welding undertaken without suitable exposure control measures, regardless of duration. For indoor welding that means local exhaust ventilation as the primary engineering control, with adequate and suitable respiratory protective equipment on top where LEV alone does not control residual fume. For welding outdoors, appropriate respiratory protective equipment should be provided. Any engineering controls must be correctly used, maintained and examined and tested where required, and any respirator must sit within a proper programme.

None of this is the householder's legal duty — these are duties on the welder and their employer — but it changes what you should expect to see, and it changes the practical arrangements. A welder repairing a gate inside a closed garage needs extraction at the arc, not an open window. Most mobile welders would rather bring the work outside or into a doorway for exactly this reason, and a job that has to be done in a confined space will be slower and better equipped than one done in the open air.

Welding, cutting and grinding all throw sparks and all put heat into the parent metal well beyond the joint. In a domestic setting the risks are specific and predictable: sparks reaching dry vegetation, fuel, aerosols, paint or timber; heat conducted through a steel member into a concealed void or into insulation on the other side of a wall; and smouldering that does not become a fire until an hour after everyone has left.

The practical control is to clear a generous area around the work, cover what cannot be moved with a proper fire blanket rather than a dust sheet, remove or isolate anything flammable including gas bottles and stored petrol, have an extinguisher at hand, and keep watch on the area for a period after the work finishes rather than packing up immediately. Where the metal passes through or touches a wall, floor or roof build-up, the concealed side has to be checked.

Some jobs should simply not be welded in place. Work on or near a gas installation, work inside a roof void or a cavity, work on anything that has held fuel or solvent, and work on painted or galvanized material in an unventilated space all need either a different approach or a different location. If you are having work done under a buildings insurance policy or on a leasehold property, it is worth checking whether hot work has conditions attached, because commercial policies frequently impose them.

Welding is right where the joint has to be continuous, where the piece will be painted so the repair can be hidden, and where the parent metal is sound enough to take heat. It produces the strongest and neatest result, and on a decorative item it is usually the only repair that will look acceptable afterwards.

Bolting is right where the two parts may need to come apart again, where heat would damage a nearby finish, glass or seal, and where the work would otherwise have to be done in a place that cannot be made safe for hot work. A properly designed bolted connection is not a second-class repair; it is the standard approach on much structural steelwork.

Replacement wins more often than people expect, particularly on mass-produced items. Where a gate, a bracket or a frame has corroded generally rather than failed at one point, a repair simply moves the failure along a few inches. The test is whether the metal next to the break is sound: if a screwdriver goes through it, you are paying a skilled trade to postpone the inevitable.

Mobile welding is usually priced on time and travel, with the variables being how much preparation the joint needs, whether the item can be welded in place or must be removed and returned, the process required for the material, whether a generator has to be run, how much fire protection and extraction the location demands, the amount of dressing and refinishing wanted afterwards, and whether the repair needs new material spliced in. A tidy visible repair on a decorative gate takes far longer than a functional weld on something that will never be looked at.

LokalMatch is the introduction only. Describe the item, what has broken and where it is, with a photograph if you can, once, with your postcode, and welders and fabricators covering your area can respond. There is no cost to homeowners; pros pay for the requests they receive. LokalMatch does not carry out welding, does not set prices and does not vet, rank or recommend anyone who gets in touch, so satisfying yourself about their insurance and their fume and fire arrangements is your responsibility.
