How to clean up a bad weld

Cleaning up after welding is important for several reasons, many of which are common sense, such as the project can be started and consequently finished quicker if the project does not have to begin with cleaning the area to be used. Another reason is that the welder itself will be ready to use and be safer to use if it is handled the same every day. With this in mind, cleaning up properly when the welding is finished can be accomplished by following these few simple steps.

Step 1 is to extinguish the flame by turning the valves off on the handle part of the welder, pin the valves closed, then the main valve on the oxygen tank should be closed by being firmly seated at the bottom.

Step 2 is to open the oxygen valve on the regulator and bleed off the excess oxygen located in the regulator and in the feed line. Once the pressure on the feed line has been reduced to zero, close the pin valve.

Step 3 is to release all pressure on the oxygen regulator by opening the valve completely. Leave this valve open, because if it is closed, the line will pressure back up once the tank is open again.

Step 4 is to close the valve on the acetylene line, just as with the oxygen line, by pinning the valves closed then closing the main valve on the acetylene tank.

Step 5 is also similar to step 2, except that it pertains to the acetylene line, open the valve on the acetylene regulator and bleed off the excess acetylene located between the regulator and the feed line. Once the pressure has been reduced to zero on this acetylene regulator, close the pin valve.

Step 6 is to release all pressure on the acetylene regulator; this is accomplished by opening the tank valve completely. After all the pressure has been released, leave the valve open.

Step 7 is to return all the tools used for the project to their proper storage area and coil the feed lines around the handle of the gas cylinder cart. Never remove the nozzle from the feed line when cleaning up; these nozzles prevent accidental damage to the threads used to attach the nozzle.

Step 8 is to finish cleaning the area where the project was being worked on. This could easily include sweeping as well as picking up left over metal or other materials and placing them in the proper locations, be it storage or trash.

These steps are used when cleaning up after using an oxygen/acetylene welder. With other types of welders, to get the welder ready for the next project, simply turn off the welder, roll the leads up and place them where they belong, usually either on the welder or next to the welder.

Cleaning up is important in any job or when working on any project and welding is no exception. When the area has been properly cleaned, it makes the next welding job easier and quicker to begin as things should be in their proper place and the area where the job will be worked on should be clear of any trash, dust or any other thing that could affect the work to be done. Remember, when you have completely finished welding and are ready to quit for the day, you need to clean up.
