Quality is the reason that galvanized pipe got so popular in the 1960s and is still used by people around the globe. Basically, galvanized pipes are made of steel pipes but they are coated with a protective zinc layer so the pipes can stay safe from rust and corrosion.

The applications of galvanized pipe include sewer pipelines, railing, fencing, irrigation system, scaffolding, and many other. For different purposes, you will find galvanized pipes in different variants such as we are going to discuss galvanized pipe: 320 in today’s guide.

How to weld galvanized pipe 320?

How to weld galvanized pipe 320

1: Setting up

The first step of the procedure of welding galvanized pipes after gathering all the materials is to set up the workplace according to your needs and the work to be done. Wear your welding protective gear that comes with welding gloves, apron, mask, and respirator. Next, set up a fume extractor at a very little distance from the place where you are going to weld. The fume extractor will immediately absorb all the fumes of welding so you do not feel suffocated.

2: Grinding the area

The next step you have to follow here is grinding the area of galvanized pipe to remove the zinc coating as it can prove to be dangerous while making contact with the pipeline welding machine. You can use sandpaper to manually grind the galvanized pipe or you can go with a low setting grinder to wear off the zinc coating. Grinding the galvanized pipe and wearing off the zinc coating will also help you get a perfect cut with complete accuracy and precision.

3: Placing the pieces together

The third step of the procedure is to place the steel pieces together. Set up your pieces according to your need. You must make sure the place you are using to weld is completely non-combustible and non-flammable to avoid any kind of accident or mishap. You can use a clamp to place the small pieces together for welding. If you want to weld a hole then keep the pipe on the surface with the hole facing up and start welding.

4: Welding

The next and most crucial part to follow in the procedure is to weld the pieces together by using an arc welder or other type of welder according to your work. First, you will have to choose a welding rod based on features and size that is compatible with your work. Use the arc welder in the place where the pieces meet. Start the arc welder by pressing the trigger and keep welding in a flow for the best and most efficient results. The advantage of an arc welder is that it does not create any sparks so you can work seamlessly for an effective experience.

5: Finishing

You are almost done and the last step of the procedure is here in which you have to finish the welding task with a smooth surface. After completing the welding task, you must check it for bond and you should wait for about 15 minutes so the welding flux can settle down and take its place properly. Test for the bond, if it is strong, you are all done with the welding but you might need to repeat the procedure from step number 4 until the connection is not strong.


We hope you must have gotten a clear answer for what you were for in the first place. All you have to do is follow the procedure as we explained above so there are no chances left for any confusion or complication. Also, do not forget to take precautionary measures such as wearing a full welding suit including a welding mask, apron, gloves, and respirator. Make sure the place comes with good ventilation so you do not feel uncomfortable.
