Welding: All our tips for soldering

To weld your own fittings plumbing there are two methods, electric arc or with a mixture of oxygen and acetylene gas. Here is how to achieve the proper solder secondePour your plumbing fittings: - properly clean parts - welding at the right temperature - cool your rooms.

How to Solder: removing impurities

Clean room

Your pieces must be carefully sanded with emery cloth, then wiped with a clean dry cloth. Brush your pieces of solder paste , auto-stripping. Solder paste your parts rid of impurities under the action of heat.

Turn your welder and check the temperature

Make the room blushing

Open the gas supply valves and operate the automatic switching by directing the tip of the iron so that it does not burn. Heat use is regulated by acting on the mixture and the gas flow. She is correct when the flame (the stinger) is short and blue , almost white.

How to pack?

Solder paste applied previously will facilitate the work of the solder. Introduce the flame to the parts to be welded. For example, if it is a fitting on a copper tube, turn it so as to heat the entire circumference uniformly. Good heat is reached when the copper is orange yellow. Discard the flame and then submit the welding rod. It should melt instantly on contact with metal and infiltrating into the joint.

The trick, in fact, is not to form a loaf shape on the surface but to enter the filler metal as deeply as possible between the two assembled parts. You can warm up the weld to complete the work.

But if the glue stick, if you make large blocks, welding is missed, the pieces are probably not hot enough. It must then start over.

How to Solder: cool your room

Impoundment of the room

If you must perform several welds in the same room, a fitting example, immerse it in water to cool. Otherwise, it is best to let him return to normal temperature in the open air.

Double check your soldering. If you notice a defect or a crack, start again. A proper weld does not blister. It is not necessary to file .

How to Solder: alternatives
