The MiG-25 made its first public appearance in 1967. And as America influenced the MiG-25's development with its XB-70, B-58, and A-5 Vigilante, the MiG-25 also influenced the development of America’s super fighter the McDonnell Douglas F-15 Eagle. The American’s...
I have worked with the MIG process for 40 plus years and with the pulsed process close to 25 years. When I first started evaluating pulsed equipment the Panasonic rep was
In comparison, MIG can be used in higher production applications where increased throughput is important, and it’s a good option for a wide variety of metals. A typical travel speed in TIG welding is 4-6 inches per minute. With MIG welding, travel speeds are much higher; 6 inches per ...

Glucose repression thus involves three consecutive negative steps: glucose inhibits Snf1, which inhibits Mig1, which represses target genes [23, 25, 26]. There is also a glucose induction pathway in yeast, which activates genes required for uptake and metabolism of glucose (Figure 1). It works...

表1 单一热源模型模拟变形量与实测结果对比Table 1 Comparison between simulated deformation of single heat source model and measured results 两种热源对比发现,采用双椭球热源模型时,焊缝端变形程度小于3D热源模型,这可能是由于双椭球深度方向热输入小或者热源分布更加均匀。

I pulled out my DC clamp meter to check how much the current flow varies from the actual setting. It turned out to be around 25%-30% in variable scenarios but never more than that. Which means, if you set your amp settings at 100A, you’ll get an actual output of around 75A which...
