    Shenzhen ZHAOWEI Machinery & Electronics Co., Ltd was established in 2001, which is State High-Tech enterprise for gear transmission design and manufacturing. Our DC motors are mainly related to automotive components, industrial equipment, smart home, medical equipment and standardized gear box, providing services and solutions for the world's intelligent driving.
  Arc welding processes require the welder to use good workmanship in order to produce sound welds. Poor technique such as an overly long distance between the electrode and the work piece (arc length) can make the difference between a smooth, strong weld and one that’s full of defects and prone to failure. Learning the skill requires time and patience, along with a significant volume of supplies. 

In traditional arc welding, the welder must strike and maintain an electrical arc between an electrode and the workpiece, or coupon, completing an electrical circuit driven by a welding power supply. The arc heats an area of the coupon to thousands of degrees centigrade, hot enough to melt the coupon metal and a filler metal so that the two can combine to form a strong bond. Arc welding can be classed by whether the electrode itself melts to become the filler material (consumable-electrode arc welding) or whether the filler material comes from a separate source (non-consumable electrode arc welding).

Learning to weld has traditionally been a matter of trial and error. It's an art as much as a skill, requiring students to go through coupon after coupon until they absorb the technique needed to consistently turn out good product.
