Welding is a great way to join two pieces of metal together. The process is simple, but there are a few techniques that can help make the process easier. This blog post will discuss one of those techniques, Nice welding technique, how to have a beautiful weld.
How to have a beautiful weld
For the welder, the most important thing is to create quality welds. But not everyone makes good welds. So how to have beautiful welds, the following article Weldfaq will introduce to you the basic techniques to create beautiful and quality welds.
Many welders, when they first learn to be familiar with manual arc welding, often do not realize what is a good weld, a quality weld, where is a faulty weld, looking at the weld does not know what is being encountered. What is the error to adjust the machine operation accordingly.
How to create beautiful, quality welds like the picture above???
1. Choose the appropriate type of welding rod, reasonable size:
To have a beautiful weld, you must first choose the right type of welding rod. The type of welding rod must be suitable for the solder in terms of the type of material, the type of cover, etc. To choose the right type of welding rod based on the solder, please consult the welding consumables manufacturer and supplier. device…
Depending on the thickness of the solder, we use different sizes of welding rods
2. Reasonable arc length
Basically welding arc length should not exceed welding rod diameter
When the arc length is too short, it can cause the arc to be unstable, which can cause the arc to be extinguished, the puddle to harden faster and create high solder flakes.
The arc is too short, the solder puddle hardens and creates scabs
An arc that is too long will cause splashing, slow precipitation, and porosity.
3. Set reasonable welding current
However, according to the type of electrode used, the device used needs to set the forward, reverse or alternating current. Need to make sure you equipment is set up properly before soldering.
Faulty weld phenomenon due to too high welding current. Wide, flat and discontinuous welds
The phenomenon of defective welds due to the welding current is too low. High solder joints, no penetration
4. Adjust welding speed and welding rod angle reasonably
Moving the welding rod too quickly causes the faulty weld to become undulating, broken, liquid metal slag, and splashes a lot.
Welding speed is too fast, the weld becomes undulating, broken, liquid metal slag, splashes a lot
Welding too slowly will create convex solder scales and do not melt. The arc lost heat cannot melt the solder.
Hopefully what we have just shared can help the welder to know how to weld properly to create beautiful, quality welds that are effective in the working process.
