Internal Welding Monitoring Device of Spiral Submerged Arc Welded Pipe Based On AT89C51 Single-Chip Microcomputer System

Submerged Arc Welding: A Review

In industries and research organizations most widely used welding methods are shield metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW) and submerged arc welding (SAW). The SAW process is often preferred because it offers high production rate, high melting efficiency, ease of automation and low operator skill requirement. This review will be very helpful for...

Monitoring of Arc Welding Process Based on Arc Light Emission

Thermaltransport Phenomenon of Submerged Arc Welding Process

Original scientific paper In present work, thermal transport considering heat radiation by oval heat source shape and heat transfer of molten moving electrode was presented. In present paper, an analytical solution was presented by aggregating temperature increments caused by applying liquid metal and heat radiation of moving electrode. The assumptions for the study were heat source of temperat...

Design of Automatic Mower Based on Single Chip Microcomputer

With the development of city construction, there are increasing demands on the greening, but the traditional mowing way is always by man hand, which has low efficiency, high noise, and also has the existence of security risks. In this paper, a kind of automatic mower is designed based on the Single Chip Microcomputer, automatic mower has high efficiency, low noise, and also can avoid the staff ...

Effect of Submerged Arc Welding Parameter on Crack Growth Energy on St37

In this article the influence of welding parameters such as electrical current, feed rate and stick out on crack growth energy was investigated. Therefore, prepared specimens were welded in various conditions. Using the Minitab software, 18 states of 36 possible states were chosen and applied. Then a crack was crated on the weld metal and the force-displacement diagram was plotted. Comparison o...
