Draft Edits For Peer Review (Thermite)
These changes have already been made to the thermite article:

Was:

"However, defects such as slag inclusions and voids (holes) are often present in such welded junctions and great care is needed to operate the process successfully. Care must also be taken to ensure that the rails remain straight, without resulting in dipped joints, which can cause wear on high speed and heavy axle load lines."

"However, defects such as slag inclusions and voids (holes) are often present in such welded junctions and great care is needed to operate the process successfully. Both Finite Element Analysis and experimental analysis of thermite rail welds has shown that weld gap is the most influential parameter affecting defect formation.  Shrinkage cavity formation and cold lap welding defects are reduced by increasing thermite temperature, increasing preheat, and increasing gap.  However, these all promote microporosity.  Care must also be taken to ensure that the rails remain straight, without resulting in dipped joints, which can cause wear on high speed and heavy axle load lines."

These changes have already been made to the thermite article:

Was:

"Because standard iron-thermite is difficult to ignite, burns with practically no flame and has a small radius of action, standard thermite is rarely used on its own as an incendiary composition. It is more usually employed with other ingredients added to increase its incendiary effects."

"Because standard iron-thermite is difficult to ignite, burns with practically no flame and has a small radius of action, standard thermite is rarely used on its own as an incendiary composition. Increases in gas content of the reaction products of a thermite increases the heat transfer rate (and therefore damage) of that particular thermite blend. It is more usually employed with other ingredients added to increase its incendiary effects."
