How to Weld

Introduction

If you have never tried to weld the metals welding may turn out out to be quite complicated for you. But there is no need to hesitate as each activity is possible to be comprehended and mastered if the one makes some efforts. You will need the welding inverter. It is possible to make your own inverter. That may seem to be a good idea but it is still recommended to buy one. As soon as you learn to weld well you will be dissatisfied with the properties of the homemade device and you will finally buy one. Having learned to weld well one may solve a lot of problems concerning fixing various things and even make some useful things as swing for the children or an arbor.

Choose the inverter which has the smooth ranging of background supply. In that way you will have the opportunity to adjust it in accordance with the peculiar features of the metal that you are welding. You will also need the special protecting equipment that is aimed to defend your skin and eyes from the negative effects of welding such as hot temperature, flashing lights, sparks and electric current. The basic set of that equipment normally includes the special protective mask with the dark UV filtering glass. The electric arc releases the large amount of UV radiation which may damage your eyes badly. The inexperienced welders were reported to get the serious cornea burning which made them bedridden for a couple of days. You will also need pants, gloves and jacket made of the fireproof cloth. Generally they are made of heavy canvas soaked with the special heat resisting agent. The sparkles from the electric arc may burn the cotton gloves.

Do's

  • Attach the work clamp firmly to the detail.
  • Fix the electrode between the electrode holders.
  • Adjust the background current according to the characteristics of the metal you are going to weld.
  • Now you may lighten the electric arc. Imagine that electrode is a pencil. It should be placed in the angular position against the metal surface.
  • Move the electrode along the surface at the speed 2 inches per second. You will see the sparkles.
  • Now touch the metal surface with the electrode and list it slowly for 3 mm above the metal surface. The electric arc will lighten and remain active. Try to retain that small distance between the electrode and electric arc in the process of welding the whole seam.
  • Move the electrode aside slightly if it got stuck to the surface.
  • Practice retaining the steady electric arc during the process of welding.
  • After that you may start running a bead. Move you electrode to the sides slowly and slightly.
  • Imagine that you are dragging the layers of the melt metal against the seam.
  • You should get the smooth even seam with the waves of the melted metal on its bead as a result.

Don'ts

Test your skills first

Don't try to weld something that you need if you weld for the first time. You may spoil the detail. Try to practice using the spare piece of metal. Prepare the bucket of cool water to throw the hot detail in if something goes wrong.

Don't weld on the wooden work desk

The sudden separate spark may set it on fire the wood.

Don't use old electrodes

The old electrodes won't provide the even electric current. You will lose the patience using the old electrodes and the process of welding won't seem to be that captivating to you.

No flammable agents or solutions close

Don't weld if the flammable agents or objects are situated closer than several meters to the object of welding. Even the left outs of the used electrode are able to set fire.
