When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.

How to tell the difference between "easy" and "pro" questions:

An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)

A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).

Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.

When deciding between easy and pro, err on the side of pro. Most questions will be pro.

* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

Here is some additional information Cracks in the Weld Metal

We can divide weld metal cracks into three types: Transverse, longitudinal and crater cracks.

Transverse weld metal cracks are perpendicular to the direction of the weld. This type of crack is more common in welds that have a high degree of restraint.

Longitudinal weld cracks travel in the same direction as the weld and are often confined to the center of the weld. This type of crack may be an extension of a crack that originally initiated at the end of a weld.

Crater cracks can be formed by an abrupt weld termination if a crater is left unfilled with weld metal. These cracks are usually star shaped and initially only extend to the edge of the crater. However, these cracks can propagate into longitudinal weld cracks.

thanks for your reply , but there are three types of discontinuities, one is circle , the other , is centreline ....how about the third is it polygonal...? thanks again

longitudinal discontinuities

The radiographic image shows three longitudinal discontinuities along the weld length. The discontinuities are circled.

... centerline cracks ...

Fixing the soldered joints may perhaps be aimed at responding to the centerline (centreline) cracks or to those essentially intersecting ones on the soldering axis.
