Standard pulse welding simply welds manifold pipes together. But the weakness is that the pipes become thinner after welding, with structural changes and a shorter operation life. However, welding with the addition of fusible material the same as that of the pipes does not compromise pipe-wall thickness, but rather strengthens and extends durability.
